Mean Girls costumes are some of the most forgiving I style, because almost everything in the movie is ordinary early-2000s clothing with one character detail on top. Hair carries most of the work: blonde for Regina and Karen, big brunette curls for Gretchen, long red waves for Cady, purple streaks for Janis. The rest comes from closet basics, thrift finds and a few pink accessories. Below you'll find solo looks, duos and full groups covering Regina George, Cady Heron, Karen Smith, Gretchen Wieners, Janis Ian, Damian and more of North Shore. Each one lists clothes, hair, makeup, shoes and props, and I've noted where heels or short hems will cause trouble on a long night.
Wigs for the Plastics Without Dyeing Your Hair
Hair is how people tell these characters apart, so a wig is usually the one thing I tell people to spend a little more on. A cheap costume wig in a plastic bag can be made to look much better with some care.
- Shake the wig out and brush it gently from the ends upward with a wide-tooth comb. Cheap wigs shed at first, so do this over a bin, not on the way out the door.
- Trim a blunt costume fringe or overly thick ends with sharp scissors, a little at a time. Most party wigs look fake because they're too heavy and too even.
- Keep synthetic wigs away from hair dryers and oven doors unless the label says heat-friendly. Ordinary synthetic fibre frizzes or melts near high heat and won't recover.
- Wear a wig cap and pin the wig at the temples and nape. Regina's smooth side part needs the front to sit flat, and a loose wig slides back over an evening.
- For Gretchen's volume, tease the roots and spray. For Cady's waves, braid the wig loosely overnight and undo it the next day.
- For Janis, clip-in purple strands over your own dark hair are easier than a full wig and much cooler to wear.
1. Regina George Pink Cardigan Costume
Regina's pink cardigan look is the one people picture first, so it's a safe pick for a solo costume. Layer a fitted pink cardigan over a white graphic tank, then add a red or black mini skirt, sheer tights and pointed pink pumps. The hair is non-negotiable: a straight blonde wig with a smooth side part, or your own blonde hair pressed flat. Glossy makeup suits her, with pink blush, neutral shadow, mascara and lots of lip gloss. I'd carry a small shoulder bag, a chunky flip phone and a homemade Burn Book. Swap the pumps for pink ballet flats if you'll stand for hours. A pink manicure is a small touch, but people notice it when you're holding the book.
2. Regina George Cutout Tank Costume
Regina's cut-up white tank is easy to spot and costs almost nothing to make. Start with a plain white sleeveless top and cut two neat circles in the chest. Wear a bright purple camisole or fitted tee underneath so you're covered and comfortable. A black mini skirt, nude tights and pink pumps or flats finish the outfit, with a long smooth blonde wig, rosy makeup and glossy lips. A pink shoulder bag and a stack of notebooks are her props. Cotton jersey curls inward once it's cut, so I trace the circles with a glass and run a line of fabric glue or clear nail polish around the edge to stop it rolling. Fashion tape keeps the two layers from shifting.
3. Regina George Bunny Costume
Regina's party bunny can be done with full coverage and still read as her. I use a white strapless or sleeveless fit-and-flare dress in place of a bodysuit, with white tights, white gloves and low silver or white heels. A soft bunny-ear headband and a pom-pom tail pinned at the back cover the animal part. Wear a long blonde wig with polished curls, or straighten your own hair with a side part. Party makeup works here: pink blush, shimmery neutral shadow, winged liner and glossy lipstick. A small white handbag holds your phone and keys. White gloves show every mark, so I put them on last, after makeup and hair, or they're gray before you leave.
4. Regina George Lacrosse Costume
Sporty Regina is a red sleeveless athletic jersey over a fitted white tee, with a matching pleated athletic skirt, white crew socks and supportive white sneakers. Buy a plain jersey with no team logos and add a number with iron-on vinyl or fabric paint. Iron-on vinyl needs a firm press and a cool peel on most jersey mesh, and it lifts if you rush it. A blonde ponytail or long blonde wig keeps the hair right and out of your face. Natural makeup is enough: rosy cheeks, mascara, pink lip balm. Skip the full stick and carry a lacrosse ball or light sports bag. It's warm enough for an outdoor party and lets you run around.
5. Regina George Spring Fling Costume
Regina's Spring Fling entrance is a funny one to recreate because she shows up in a brace and still wins the crown. Wear a soft pink sleeveless dress with a fitted bodice and a knee-length skirt. Over it, I build a light brace from white elastic, craft foam and fabric panels, flexible enough to sit down in. Curl long blonde hair loosely and set a small plastic floral crown on top. Pink cheeks, a little shimmer, mascara and rose gloss suit the formal mood. Nude pumps match, though block heels or flats are kinder for a long evening. A tiny pink clutch and a mock dance ticket finish it. The brace is the joke, so keep it clean white and very visible.
6. Cady Heron Red Top Costume
Cady's Plastics-era outfit is made from clothes you'll actually wear again, which is why I like it. Choose a fitted red wrap top or long-sleeve V-neck with dark bootcut jeans. Black pointed pumps, ankle boots or flats all work. Long red hair does the heavy lifting here: a wavy auburn wig, or your own red hair with a centre part. Keep makeup fresh with light foundation, mascara, peach blush and neutral gloss. Carry a school binder, a simple shoulder bag and a name tag reading “Cady,” with a small Burn Book for extra context. Wrap tops slide open when you reach for things, so I put a small safety pin or a strip of fashion tape at the cross-over point.
7. Cady Heron Scary Ex-Wife Costume
Cady's ex-wife costume is the joke version, and it's a relief for anyone who doesn't want to wear a mini skirt. Start with a modest white bridal-style dress from a thrift store, with a white long-sleeve top underneath if it's cold. Add a light white veil, elbow-length gloves and white flats that look a bit worn. Gray eyeshadow, pale face makeup and smudged liner give a ghostly look without any gore. A messy dark auburn wig and removable novelty teeth are the details that make it Cady. Wilted fake flowers or a paper marriage certificate make good props. Novelty teeth make talking hard, so I keep them in a pocket and put them in only for photos.
8. Cady Heron Mathletes Costume
For Mathletes Cady, the jacket is the whole costume. Find a blue-and-gold varsity jacket or a plain blue zip-up, and wear it over a white collared shirt with dark straight-leg pants or a knee-length skirt. White socks with sneakers or loafers keep you comfortable. Style an auburn wig in natural waves and keep makeup minimal. I make the Mathletes patch from felt and attach it with safety pins rather than glue, so the jacket comes back undamaged. Felt letters glued onto nylon jackets tend to peel off anyway. Carry a calculator, notebook, pencil and a mock competition card, and a light medal if you want a win. No heels and no dress required.
9. Cady Heron Spring Fling Costume
Cady's final dance look is the subtle option. Pick a sleeveless blue mini or knee-length dress with a simple fitted shape, nude or silver block heels, small stud earrings and a metallic clutch. Loose auburn waves and a light floral crown handle the hair. Soft makeup suits her: peach blush, mascara, neutral shadow, rosy lips. The prop that tells people who you are is a plastic crown snapped into pieces, since Cady breaks hers and hands it out. Snapped plastic leaves sharp edges, so I sand them or cover them with tape before the night. Without the broken crown it's just a pretty blue dress, which is fine if you want a party outfit more than a costume.
10. Cady Heron First Day Costume
First-day Cady is the comfortable one, because she hasn't been made over yet. A loose plaid button-down over a basic crewneck tee, relaxed jeans and brown sneakers set the tone, with a green utility jacket or plain backpack on top. Leave long auburn hair natural and a little tousled with almost no product. Makeup should barely show: tinted moisturiser, brushed brows, mascara and lip balm. A school schedule, a campus map, a notebook and a pencil case sell the new-student idea. The clothes should look less put together than her later wardrobe, so don't iron the shirt. I'd suggest this one for cold nights, daytime events or a costume you need by tonight.
11. Karen Smith Mouse Costume
Karen's mouse costume is one of the easiest looks from the movie. Wear a fitted gray long-sleeve dress, or a gray top with a matching skater skirt, plus opaque gray tights and black flats or low heels. Round mouse ears on a headband and a soft fabric tail pinned to the skirt cover the rest. Long blonde hair should be worn straight with a centre or slight side part. Shimmery gray shadow, pink blush, mascara and gloss keep the makeup playful. A wedge of craft-foam cheese is my favourite prop here. For the tail, I stuff a tube of gray jersey lightly and sew a short length of wire inside so it curves instead of hanging straight down.
12. Karen Smith Weather Reporter Costume
Karen ends the movie as the weather girl, and that makes a less obvious solo costume than the mouse. Wear a fitted pink top with a coordinated knee-length skirt and a light blue cardigan, plus nude pumps or pink flats. Smooth blonde waves, pink blush, mascara and high-shine gloss suit her. Carry a toy microphone with a generic weather symbol and a handmade forecast card showing a sunny sky. Small felt clouds and suns stitched onto a blue shoulder bag help too. Without the props this is just a pink outfit, so I'd make the microphone big enough to see across a room. A painted cardboard tube with a foam ball on top works.
13. Karen Smith Pink Plaid Costume
Karen's everyday Plastics look is a pale pink fitted top, a pink plaid mini skirt and a cropped cardigan. Add nude tights with pink pumps, or Mary Jane flats for a school feel. Wear long blonde hair straight and pin a small black bow near the crown. Makeup is sweet and glossy, with soft pink shadow, rosy cheeks, mascara and pale gloss. A tiny pink purse, a flip phone and a notebook covered in weather doodles finish it. If the skirt is shorter than you like, wear fitted shorts underneath or choose a knee-length plaid. Plaid skirts from fast-fashion racks are often printed off-grain, so check that the lines run straight before you buy.
14. Karen Smith Spring Fling Costume
Karen's formal look starts with a light blue satin or chiffon dress with a simple flared skirt. Silver ballet flats, a sparkly mini bag and delicate costume jewellery keep it light. A long blonde wig in loose curls gives the dance-night finish. Apply icy blue shadow lightly and balance it with mascara, pink blush and gloss. A small floral crown and a folded dance program sit well together, and a sunny forecast card tucked in the bag is the Karen-only clue. Satin shows every crease from sitting in a car, so I steam it at the last minute or choose chiffon, which hides wrinkles better. Pick secure straps; you'll be dancing.
15. Gretchen Wieners Pink Plaid Costume
Gretchen is the most accessorised of the Plastics, and her costume should look slightly over-thought on purpose. Wear a hot pink fitted top with a pink-and-brown plaid skirt and a cropped cardigan if it's cool. Nude tights with strappy pink sandals, low heels or flats all work. Her hair needs volume at the crown and loose curls through the ends, so I tease the roots and use a big barrel curler. Brown liner, rosy blush and glossy pink lips suit her. A designer-style shoulder bag, a flip phone and a homemade Burn Book go in hand. A small gold hoop or pendant necklace adds the extra Y2K layer that sets her apart from Regina.
16. Gretchen Wieners Cat Costume
Gretchen's cat look can be done fully covered and still feel like a party outfit. Start with a black long-sleeve fit-and-flare dress, opaque tights and black ankle boots, then add velvet cat ears, a soft detachable tail and short black gloves. Brunette hair should be big and curly, either your own or a voluminous brown wig. Draw a tiny nose and fine whiskers with eyeliner, and add smoky brown shadow and pink gloss. A jewelled collar necklace and a small black bag give it Gretchen's polish. Black fabric shows lint and hair under a flash, so I keep a lint roller in the bag. A ball of yarn makes an easy, light prop.
17. Gretchen Wieners Spring Fling Costume
For Gretchen's Spring Fling, choose a pink or rose formal dress with a fitted bodice and a knee-length flared skirt. Add strappy silver heels, a metallic clutch and sparkly drop earrings. Bouncy brunette curls with plenty of lift at the crown are the key to her. Soft brown shadow, winged liner, pink blush and glossy lipstick make up the face. A floral crown and a folded dance ballot are her props, and a gold initial necklace is a nice nod to her. Big curls drop fast in a warm room, so I set them with spray before the crown goes on. Block heels or embellished flats are kinder if you'll be on your feet.
18. Janis Ian Black And Purple Costume
Janis is the dark, arty contrast to all that pink, and her look is easy to thrift. Wear a black graphic tee over a purple long-sleeve mesh or fitted top, with a black midi skirt or loose black pants, striped tights and chunky lace-up boots. Purple streaks in straight dark hair are her signature; clip-in extensions or temporary colour spare your own hair. Smoky purple shadow, black liner, muted lipstick and pale foundation finish the face. I'd pile on silver necklaces, safety-pin jewellery and a studded belt. A sketchbook full of doodles is her prop. Temporary hair colour sprays can rub onto collars when it's damp out, so set them with a little hairspray once dry.
19. Janis Ian Spring Fling Costume
Janis at the dance keeps her edge, so don't put her in a frilly gown. I'd style her in a black or deep purple suit with a fitted vest, a crisp white shirt and a narrow tie. Black ankle boots or polished loafers fit her better than heels. Straight dark hair with purple streaks, smoky liner, plum shadow and berry lipstick keep the face hers. A silver chain necklace and several rings add texture against the tailoring. Carry a small sketchbook, a floral crown or a mock dance ticket. A thrifted suit rarely fits perfectly, and rolled cuffs and pushed-up sleeves suit her better than tailoring anyway. Pair her with Damian and the duo is done.
20. Damian Blue Hoodie Costume
Damian's look from the movie starts with an oversized blue hoodie over a plain tee, loose black pants, dark sneakers and big sunglasses. Pull the hood up and wrap a blue scarf loosely at the neck to give it shape. Natural makeup is fine, or neat brows and a little foundation for photos. A handmade sign or a notebook labelled for a North Shore class works as a prop, and a crossbody bag holds the essentials. Most of it is probably in a closet already, so it's my first suggestion for someone with a party tonight. The one tip: sunglasses at night make stairs hard to see, so push them up on your head when you're moving around.
21. Aaron Samuels Football Costume
Aaron's athlete version is a generic blue-and-gold football jersey over a white compression shirt, with athletic pants or relaxed jeans, tall sports socks and clean sneakers. Carry a football and hold a light helmet under one arm; nobody wants to wear a helmet at a party for more than a minute. Short brown hair with a slightly messy finish suits him. Makeup is optional, though matte skin and lightly filled brows help in photos. A backpack and a mock class schedule showing advanced math tie him to Cady. Use iron-on numbers and felt patches instead of any real team logos. Jerseys run boxy, so size down if you want it to sit like a real one.
22. Aaron Samuels Classroom Costume
For a casual Aaron, wear a fitted blue crewneck under a gray zip-up hoodie, with medium-wash straight jeans, white sneakers and a simple backpack. Brush short brown hair slightly forward. No theatrical makeup is needed. The clue that gives it away is a paper calendar showing October 3, which fans will get right away. A math textbook, a pencil and a generic school ID on a lanyard add context. This is the version I'd send someone who doesn't want to wear a full uniform, and it pairs neatly with Cady in her red wrap top, auburn hair and dark jeans. Make the date on the calendar big and bold; small print won't show in photos.
23. Kevin G Mathletes Costume
Kevin G's Mathletes look is a blue-and-gold varsity jacket over a white collared shirt, with dark trousers, a striped tie and black sneakers or loafers. Keep short dark hair neat and grooming simple. A homemade Mathletes patch on the jacket, a calculator, a clipboard, a pencil and a mock scorecard cover the props, and a ribbon or light medal adds a win. A small notebook of math-themed rhymes is a funny extra for anyone who knows the character. I'd avoid stiff dress shoes, since this is a costume you'll be walking in all night. He stands fine on his own, but he's at his best next to Cady in a matching jacket as part of a Mathletes group.
24. Ms. Norbury Math Teacher Costume
Ms. Norbury is my favourite pick for teachers and adults who want a low-key reference. Wear a patterned button-down blouse, a neutral cardigan and a dark knee-length skirt, with opaque tights and brown loafers or low ankle boots. Shoulder-length brown hair in slightly messy waves and natural makeup with soft blush and neutral lipstick suit her. Carry math worksheets, dry-erase markers, a calculator and a travel mug, with a faculty badge on a plain lanyard. A canvas tote holds it all and adds to the busy-teacher look. This one is comfortable enough to wear to work on Halloween. Pair her with Mathletes Cady or Principal Duvall for a staff-room theme.
25. Principal Duvall School Costume
Principal Duvall comes straight out of workwear. Start with a dark gray or navy suit, a white dress shirt and a plain tie, plus polished black shoes and a black belt. Short or close-cropped hair and minimal makeup keep it neat. A clipboard, school announcements, a whistle and a generic principal badge cover the props. A blue folder marked “Student Assembly” is the detail I'd add first, since it tells people the role without anything complicated. Choose a lightweight suit and cushioned shoes, because a wool suit in a heated room gets uncomfortable fast. On his own he looks like a man in a suit; next to the students, he makes the group.
26. Plastics Wednesday Pink Group Costume
On Wednesdays they wear pink, which makes this the easiest group of four to organise. Regina wears a pink cardigan, a white tank, a red skirt and pink heels. Gretchen takes a hot pink top, a plaid skirt, brunette curls and strappy sandals. Karen wears a pale pink fitted shirt, a pink plaid skirt, a black hair bow and flats. Cady wears the red wrap top, dark jeans, black pumps and long auburn hair, the one red note in a sea of pink. Everyone gets glossy makeup, small shoulder bags and big flip phones, with one Burn Book and one Wednesday dress-code card between you. I'd assign hair first; four people in pink only read as four characters if the hair colours differ.
27. Plastics Halloween Party Group Costume
The Halloween party trio puts Regina in white bunny ears, Karen as a gray mouse and Gretchen as a black cat. I use modest fit-and-flare dresses as the base for all three, with opaque tights and flats or ankle boots. Regina needs a blonde wig and white ears. Karen also wears blonde hair but adds round gray ears and a fabric tail. Gretchen has big brunette curls, black cat ears and a jewelled collar. Coordinate the makeup with glossy lips, rosy cheeks and small animal details drawn with liner. Matching small handbags help. The colours are what keep this group readable, so make sure each dress is clearly white, gray or black and not three shades of gray.
28. Cady And Regina Duo Costume
This duo shows Cady mid-transformation beside the girl she's copying. Cady wears an auburn wavy wig, a red wrap top, bootcut jeans, black pumps and a school binder. Regina wears a smooth blonde wig, a pink cardigan, a white graphic tank, a red mini skirt and pink heels. Both get glossy makeup, small shoulder bags and big flip phones. Regina holds the Burn Book while Cady carries a math notebook or broken floral crown. Black and pink ballet flats work if heels aren't practical. Two wigs side by side show every difference in quality, so I'd buy both from the same place or at least the same fibre so one doesn't look shinier.
29. Janis And Damian Duo Costume
Janis and Damian are the comfortable duo, since neither needs bare arms or heels. Janis wears a black graphic tee over a purple fitted top, a black skirt or pants, striped tights and chunky boots, with straight dark hair, purple streaks, smoky liner, silver jewellery and a sketchbook. Damian wears an oversized blue hoodie, loose black pants, dark sneakers and big sunglasses, with the hood up and a funny handmade school sign. Generic North Shore badges and matching backpacks tie them together. I'd pick these two for a cold night or an outdoor party. Practise a couple of poses from the movie before photos; this pair is funnier when they act like the characters.
30. Mean Girls Full Cast Group Costume
A full cast lets each person pick a role that matches what they'll happily wear. Regina, Gretchen, Karen and Cady come in their pink, red and plaid outfits. Janis brings black and purple layers, Damian a blue hoodie and sunglasses, Aaron a blue athletic jersey, Kevin G a Mathletes jacket, Ms. Norbury her teacher separates and Principal Duvall a dark suit. Match each wig or hairstyle to the character and keep makeup polished but wearable. Share notebooks, calculators, school badges, flip phones and one Burn Book. For photos, line people up like a yearbook page. With this many people, I'd make one shared list of who is wearing what so nobody turns up as a second Regina.
Three Props Worth Making Yourself
Shop-bought Mean Girls props are hard to find, and the homemade ones usually look closer to the movie. These three show up again and again in the ideas above.
The Burn Book
Use a pink notebook or a plain one covered in pink paper. Write the title in large black marker or cut letters from glossy magazine pages for a collaged look. Glue a few old photos or printed faces inside so it holds up when someone opens it. Glitter glue looks fun but sheds on everything, so I keep it to the cover and seal it with clear tape.
Regina's Cut-Up Tank
Put the tank on first and mark the circles with a washable pen, because the position on a flat top never matches where it sits on a body. Cut small at first, then widen. Stretch knit doesn't fray, but the edges curl, so sealing them with a thin line of fabric glue keeps them flat.
The Broken Spring Fling Crown
A cheap plastic crown snaps cleanly if you score it first with a craft knife. Sand the edges or cover them in tape, then keep three or four pieces in a clutch to hand out. Cardboard painted gold is a softer option for kids or crowded rooms.
Get the Hair Right and the Rest Follows
Nearly every look above comes down to two things: the right hair colour and one detail people remember from the movie. Pink cardigans, plaid skirts, auburn waves, a blue hoodie and a handmade prop can turn cheap basics into a character. For a quick solo costume, Karen's mouse, Mathletes Cady or Regina's cut-up tank take very little planning. Groups and duos land harder because the characters explain each other. Lengthen a skirt, lower a heel or add a layer wherever your night needs it. If I were dressing a group of friends tomorrow, I'd start with the Wednesday pink four and add Janis and Damian for anyone who hates pink.
