Poison Ivy reads from across a room for two reasons: red hair against green, and leaves that look like they're growing on you rather than stuck on. Get those two right and almost any green base works, from a corset to a hoodie. I've grouped every idea below by the kind of garment you start with, so you can begin with whatever green piece is already hanging in your closet. Each one covers hair, makeup, a prop and shoes, and several are built for long nights, cold porches or school rules that ban anything revealing.
Attaching Ivy So It Survives the Whole Night
Most of these costumes fail at the same spot: the leaves. Artificial ivy garland is a wire stem with plastic or fabric leaves clipped on, and both parts behave in ways that matter once you're wearing it.
- Strip the garland into short lengths of six to ten leaves. Long runs pull on the fabric and swing loose; short ones sit flat.
- Sew each length to a strip of felt or grosgrain ribbon with a few stitches around the wire stem, not through the leaves. The leaves can still move, so they look alive.
- Attach the felt strips to the garment with safety pins from the inside, or with sew-on snaps if you plan to wear it more than once. The costume washes and the garment survives.
- Point every leaf downward. Real ivy hangs, and upward leaves read as a party decoration.
- Tuck the cut wire ends back on themselves with pliers. A bare wire end will find your skin or snag tights.
I don't hot-glue ivy to clothing. On stretch fabric the glue cracks as soon as you move, and on a cold porch it goes brittle and lets go. If you must glue, glue leaves to felt and treat the felt as the patch. Fabric leaves are softer near the face and neck; plastic leaves are tougher on skirts and boots, where they get knocked.
1. Classic Green Ivy Corset Costume
This is the version most people picture: an emerald corset covered in ivy, worn over a green bodysuit or with high-waisted shorts and opaque tights. I place the big leaves first at the neckline and hips, because those edges define the shape, then fill the centre with smaller ones pointing downward the way real ivy hangs. A long, wavy red wig and a berry lip do the character work. Leaf wrist cuffs and a light vine garland are enough of a prop. The one rule I won't bend: sew the leaves onto felt patches and attach the patches, because glue on stretch fabric cracks the first time you bend over.
2. Green Ivy Mini Dress Costume
A fitted green mini dress is the quickest base I know for this character. Velvet looks rich, jersey is the comfortable choice, and sequins catch party lights. Stitch ivy clusters at the neckline, over one shoulder and along the hem, but leave gaps so the dress still moves; a fully covered skirt swings like a lampshade. Soft red waves with a leafy comb above one ear, green shimmer on the lids and a deep red lip carry the face. Green tights and knee-high boots keep it warm enough for a porch.
3. Green Ivy Jumpsuit Costume
I steer people toward a long-sleeved jumpsuit when they want a costume they never have to tug at. It's one piece, so nothing rides up, and it's warmer than a dress outdoors. Run the vines diagonally from one shoulder to the opposite hip and keep going around one leg; the diagonal line is what makes it look grown-in. A leaf belt marks the waist. If you'd rather not wig, washable red hair spray works, though it rubs onto collars, so wear a dark one or skip the collar entirely. Flat green boots and a jumpsuit with real pockets for your phone make this the most practical option in the list.
4. Green Ivy Bodysuit And Tights Costume
A bodysuit and matching tights give you a smooth canvas that can carry a lot of foliage. Pick a properly opaque bodysuit; cheap thin ones turn see-through under flash, which you only find out from the photos. Ivy goes at the neckline, shoulders, hips and cuffs, with a few short trailing pieces. I put the decorations on fabric snaps so the whole leaf layer lifts off before the bodysuit goes in the wash. Big red curls, greens blended out toward the temples and a brick-red lip suit it, with over-the-knee boots underneath. Carry a coil of vines or a foam flower, nothing heavier.
5. Glam Green Ivy Sequin Costume
Sequins change the plan slightly. The fabric is already busy, so I use fewer leaves here and let the sparkle show between them at the neckline, waist and one shoulder. Sewing through sequins is slow; I tack leaves only at the base of the stem, where the needle can slip between rows. A glossy red wig with two small ivy clips near the crown, metallic green lids and a classic red lip match the shine. Hold a glitter-finished artificial rose. If you want shimmer on your collarbones, use cosmetic shimmer, not craft glitter, which ends up in your eyes and stays in your car for a year.
6. Easy Green Ivy T-Shirt Costume
Short on time? A plain green T-shirt will do it. Oversized, it becomes a tunic over leggings; fitted, it tucks into a skater skirt. Pin short lengths of ivy around the collar, sleeves and waist. A red wig is the single thing that makes people say the name, though a red beanie with leaves pinned on gets close. Add green liner and red lipstick, a leafy wristband and a small watering can for a joke prop. Sneakers keep it easy, and nothing here breaks a school or office dress code.
7. Last-Minute Green Ivy Dress Costume
Any green dress you own can become an ivy costume in an evening, whether it's a wrap, a sweater dress or a fit-and-flare. Safety pins hold the ivy at the waist, neckline and one sleeve and come out cleanly the next day, so the dress isn't ruined. Pin from the inside so the metal doesn't flash. Wavy hair or a red wig with a leaf headband, a quick cat-eye and red lipstick take ten minutes. Wind a spare vine around your handbag. My one warning is length: keep every strand short enough that it can't hook a chair back or someone else's costume.
8. DIY Green Ivy Skater Skirt Costume
I like a skater skirt for anyone who plans to dance, because the flare moves and gives you room to layer leaves. Pair it with a fitted green top or long-sleeved bodysuit. Sew ivy around the waistband and add clusters on the skirt with the leaves pointing down. Leave the hem mostly bare; weight at the edge flattens the flare. A shoulder-length red wig with a small leaf crown, green at the outer corners of the eyes and opaque tights with ballet flats or low boots finish it.
9. Green Ivy Cape Costume
A cape is the clever shortcut: decorate one piece and wear it over a plain green dress, leggings set or jumpsuit. Run artificial ivy along the cape edges and fasten it at both shoulders rather than at the throat, so the weight sits on your frame instead of pulling at your neck. Long red waves with a few leaves near the temples and a smoky green eye suit the drama. A staff made from a cardboard tube wrapped in brown paper and faux vines looks like wood and weighs almost nothing. I hem capes a couple of inches above the floor, because a cape that touches the ground gets stepped on within the hour.
10. Green Ivy Tulle Skirt Costume
Green tulle gives you the softest version of the character, closer to a garden sprite than a villain. Choose a lined tulle skirt, since unlined tulle scratches, and pair it with a fitted top, bodysuit or corset. Leaves go on the waistband and upper layers only; tulle can't hold weight low down and starts to droop. A curly red wig with ivy clips and fabric flowers, pastel green shadow and a red lip match the mood. Green tights tie the colours together. Use a short vine belt, because long tendrils knot themselves into tulle and won't come out.
11. Green Ivy Velvet Costume
Deep green velvet does half the work for you. The pile catches light, so I keep the ivy to the neckline and waist and let the fabric show. A few gold leaves add depth without losing the green. Velvet marks easily, so pin through the seam allowance or along existing seams where any holes won't show. A dark auburn wig in smooth waves with a velvet headband, olive shadow and burgundy lipstick suit the richer palette. Carry a single oversized fabric flower. It's warm, which makes it a good pick for a chilly night.
12. Green Ivy Maxi Dress Costume
A green maxi dress makes a graceful, covered-up Poison Ivy. Look for a defined waist and enough skirt to stride in. I run the vines over one shoulder, around the waist and down a single side of the skirt; one long line makes you look taller, while scattered leaves on a maxi just look busy. A leaf comb keeps the red waves off your face. Swap the prop for a vine-covered clutch, and hide flats or low wedges under the hem. Check that every vine ends well above the floor before you leave.
13. Green Ivy Pants Costume
Trousers are underrated for this character. High-waisted green pants with an emerald blouse, a corset-style top or a structured vest look sharp and cover everything. Put leaf appliqués on one shoulder and the waistband, then run them down the outer seams of the pants, which is the line people see as you walk. A side-parted red wig, dark green liner and red lipstick keep the face clear. A leaf belt and cuffs, plus a clipboard or small artificial plant as a greenhouse prop, round it out. This is the one I'd suggest for an office party or a strict school rule.
14. Green Ivy Leggings Costume
If you'll be walking a neighbourhood with kids, start here. Green leggings with a long tunic, a sweatshirt or a velvet top let you move, crouch and carry. Ivy garlands go around the shoulders and waist and down one lower leg, held with hidden stitches or safety pins. A red high ponytail or your own red curls, green mascara and a bright lip are enough. A leafy headband and a vine-covered tote for snacks and wipes make sense, and athletic shoes or flat boots carry you through a long evening.
15. Green Ivy Hoodie Costume
A green hoodie with joggers is the warmest Poison Ivy there is, and I'd happily wear it to an outdoor trick-or-treat. Sew leaves around the hood edge, shoulders and cuffs, and leave the zip and front pocket working. Let a red wig fall from under the raised hood, or stitch red yarn curls inside it for a handmade touch. Around the face I only use soft fabric leaves; stiff plastic ones scratch your cheek every time you turn your head. Fingerless leaf gloves and a little succulent finish it.
16. Green Ivy Fairy Costume
Mixing the botanical villain with a fairy silhouette works if the wings stay small. Wear a green corset-style top over a layered knee-length skirt, or a dress with an uneven leafy hem. Choose translucent wings narrow enough to pass through a doorway, with rounded tips. I wrap the wing straps in ivy too, which hides the elastic and ties the wings to the outfit. A curly red wig, pointed leaf crown and green shimmer bring back the Poison Ivy side, and a vine-wrapped wand is plenty. Detachable straps help when you have to sit in a car.
17. Green Ivy Woodland Costume
For a woodland take, I mute everything. A moss-green dress or tunic over brown leggings, with mixed ivy, fern and small fabric flowers layered at the shoulders and hem, looks like the forest floor rather than a party store. Braid an auburn wig loosely and weave narrow vines through it. Olive shadow, brown liner, drawn-on freckles and a soft berry lip suit the earthy palette. A brown fabric belt and a basket of greenery stand in for jewellery, and brown lace-up boots ground it. Please skip real plants: they wilt in a couple of hours, shed everywhere and can irritate skin.
18. Green Ivy Flower Garden Costume
Flowers add colour, but they need a plan. I cap the palette at three flower colours, say pink, purple and yellow, and cluster them on one shoulder and one hip. Spread evenly, they look accidental; grouped, they look planted. Use an emerald dress, romper or jumpsuit as the base, with a floral crown repeating the same colours over a long red wig. Rosy blush and a little coloured liner alongside the green shadow link the face to the flowers. Removable flower clips on green boots and a tiny watering can carry the garden idea down to your feet.
19. Green Ivy Catsuit Costume
A catsuit is the closest you'll get to the comic silhouette, and it covers more than separates do. Buy an opaque one with a sturdy zip and real stretch. Sew leafy panels along the shoulders, sides, hips and calves, and keep the elbows and knees mostly clear, because foliage on a joint pops off the first time you sit. Big brushed red curls, graphic green liner and a matte red lip suit the sleek line. Elbow-length gloves with leaf appliqués and flat knee boots in the same green complete it. Try the whole thing on and sit down in it before the night; that's when a catsuit shows its problems.
20. Green Ivy Two-Piece Costume
A matching crop top and high-waisted skirt give you a modern two-piece. For more coverage, swap in a longer fitted top or wear green mesh underneath. I keep the ivy asymmetrical here: a cluster at one side of the neckline, another at the opposite hip, a few on the hem. A copper-red wig with leaf clips on one side, smoky green eyes and a red lip, vine arm cuffs and green block-heel boots over opaque tights finish it. The bonus is that both pieces go back into normal rotation once the leaves come off.
21. Plus-Size Green Ivy Costume
For a plus-size Poison Ivy, fit comes first: a green wrap dress, a stretchy jumpsuit or a supportive corset over a bodysuit, chosen because it already fits well before anything is added. Then place the foliage at the neckline, waist and hem to draw clean lines. I sew every leaf onto ribbon or felt strips and attach the strips, so the stretch in the garment is never stiffened by glue or tight stitching. A long red wig with face-framing waves and a flexible leaf crown carry the character. A flower-covered bag that holds your things, plus wide-fit ankle boots, keep it comfortable all night.
22. Modest Green Ivy Costume
A long-sleeved maxi dress gives you full coverage with no loss of character. I'd pick a breathable fabric, since a covered costume gets warm indoors fast, and belt it with a soft vine sash. Leaf appliqués go at the shoulders and cuffs and along the lower skirt, kept away from your face. A low red braid with a simple ivy headband and muted red lipstick keep it calm. Carry a small potted plant, which suits a family party. A matching capelet adds warmth. Stitch the vines short and tight so nothing trails behind you.
23. Green Ivy Romper Costume
A romper moves like shorts and looks like a dress, which makes it a good choice for crowded parties. Pick a structured one with a comfortable inseam, or wear fitted shorts underneath. Leaf clusters go at the neckline, waist and leg openings, and I add a separate ivy shoulder piece that pins on and off. Bouncy red curls, luminous green lids and a bright red lip suit it, with knee-high or block-heel ankle boots. Keep vines short near the legs; long ones wrap around your thighs as you walk.
24. Green Ivy Steampunk Costume
Steampunk suits Poison Ivy better than you'd expect, since both love a corset. Start with an olive corset, a green blouse and a high-low skirt with a bustle. Brown belts and bronze gears sit among the ivy on the corset and bustle. Buy plastic or foam gears, not metal ones; metal is heavy and the edges catch on lace. An auburn wig with pinned curls, goggles over a small leaf-covered hat and smoky olive eyes fit the era. A cardboard telescope wrapped in vines is the prop. I keep the foliage at the waist and shoulders so the steampunk pieces stay visible.
25. Green Ivy Masquerade Costume
For a masquerade, the mask carries the theme. Decorate a light green eye mask with small leaves and a few rhinestones, and replace stiff elastic with soft elastic before the night starts. Glue nothing within a finger's width of the eye holes, because leaves creep into your view once the glue warms. A midi or floor-length gown with leaves at the neckline, waist and one side of the skirt, a low curled red ponytail and long gloves suit the formality. A mask on a handle is kinder if you'll be wearing it for hours.
26. Green Ivy Renaissance Costume
A forest-green Renaissance gown turns Poison Ivy into a storybook herbalist. Look for puffed sleeves, a lace-up bodice and a full skirt, or layer a peasant blouse under a green overdress. Ivy goes around the square neckline, sleeves and waist, never on the hem, which drags and catches on boots. Half-up red braids with a narrow leaf circlet, blended green shadow and berry lipstick keep it soft. A fabric-bound botanical book or a basket of flowers makes a quiet prop. Brown lace-up boots handle grass at an outdoor fair.
27. Green Ivy Punk Costume
Punk Poison Ivy starts with a green plaid skirt or ripped green jeans, a black-and-green fitted top and a cropped faux-leather jacket. Pin ivy patches to the jacket shoulders, waistband and boots so they come off afterwards; faux leather keeps every needle hole, so pins beat stitches here. A vivid red high ponytail, graphic green liner and strong brows give it attitude. Leafy fingerless gloves, chunky jewellery and a vine-wrapped toy microphone add the noise. I avoid sharp studs, which scratch anyone you hug. Repeat the ivy on at least three pieces so nobody mistakes you for a generic punk.
28. Green Ivy Disco Costume
Disco Ivy is pure fun. Wear an emerald sequined wide-leg jumpsuit, or a glittering top with high-waisted flares. Attach ivy around the neckline, belt and outer legs, and let plenty of sparkle show. A big red wig in large curls with a leafy headband, metallic green shadow and glossy red lips match the era. Leaf earrings and a vine-covered round bag do for accessories. Platforms need a stable sole, and I always hem flares to the shoe you'll actually wear, because an inch too long and you'll tread on them all night.
29. Green Ivy Winter Costume
For a cold night, build the costume from knitwear. A green sweater dress, or a knit top with leggings, takes leaves well if you attach them to removable felt bands at the collar, shoulders, waist and cuffs; pinning straight into a loose knit pulls the stitches. Wear the red wig under a green beret or hood with ivy sprigs. Waterproof mascara and a tinted lip balm survive wind and drizzle. Green gloves, a vine-covered scarf and an evergreen branch work as the prop, with thick tights and insulated boots below. A forest-green coat with detachable leaf brooches can become part of the costume.
30. Green Ivy Queen Costume
The ivy queen is the showpiece: a structured green gown, a dramatic cape and a tall botanical crown. Layer leaves across the bodice and shoulders, then run longer vines down the skirt without hiding its shape. A full copper-red wig in large waves gives the crown something to sit on. I build the crown on a padded headband, never a rigid band, because a tall crown on a thin one gives you a headache within an hour. Jewel-toned shadow, sharp liner and a rich red lip suit the scale. Repeat just two or three shades of green across every element and the whole outfit reads as one costume.
Red Hair Without Dye, and Green Skin Without the Mess
The red is what makes people say the name, so it deserves a little care. A synthetic wig is the cleanest route. Cheap ones arrive flat and shiny; I brush them out with a wide-tooth comb, a section at a time from the ends up, and a light mist of water with a little fabric softener tames static. Keep a synthetic wig away from oven doors and candles, because heat frizzes the fibres for good. A wig cap and two bobby pins at each temple stop it sliding when you turn your head.
Washable red hair spray is the other choice. It works best on light hair, needs several thin coats, and transfers onto collars and pillowcases, so pair it with a dark or old top. On dark hair it barely shows, and a wig is the honest answer.
If you're going full green
Some people paint their skin green for the comic version. Use face paint made for skin, patch-test it on the inside of your wrist the day before, and keep it to the face and neck unless you have help. Press translucent setting powder over cream paint to cut down on transfer, and expect it to mark any light collar anyway. Remove it with an oil cleanser or makeup remover before soap, which only smears it around.
One Red Wig, Thirty Green Starting Points
Every version on this list comes down to the same recipe: red hair against green, leaves that look grown-in, and shoes you can stand in for hours. Corsets and catsuits get closest to the comic, while maxi dresses, trousers, hoodies and knits are kinder to cold weather and dress codes. Use artificial foliage, attach it so it lifts off, and wear the costume around the house for an hour first. My own pick is the jumpsuit, because it's warm, it never needs adjusting, and the diagonal vine line does all the talking.
