Summer school means a few extra weeks of class in the hottest part of the year, often with a bus stop in full sun on one end and an over-air-conditioned classroom on the other. Most schools also keep the same dress code in summer. Below are 20 summer school outfit ideas teens will actually want to wear, each a full outfit you can mostly pull from your own closet. With each one I've noted how it handles the heat, the cold room and the rules, because that's where summer outfits usually go wrong.

The Fingertip Test and Other Dress Code Checks
Most school dress codes don't relax in summer, and staff often watch them more closely when it's hot and everyone is wearing less. Rules differ by district, so read your own school's handbook, but these are the checks I run on any outfit meant for class:
- Shorts and skirts: stand straight with your arms at your sides. Many schools want the hem near your fingertips. Then sit down, because hems ride up several inches.
- Straps: a lot of codes ban spaghetti straps and ask for straps about two or three fingers wide.
- Midriff: raise both arms. If skin shows between the top and the waistband, many schools will call it a crop top.
- Shoes: some schools require closed toes for science labs or PE, so keep sneakers in your locker if you wear sandals.
- Underwear: visible bra straps or waistbands are one of the most common reasons students get asked to change.
If an outfit you love fails one check, fix that piece instead of giving up on the outfit. An open shirt covers thin straps, bike shorts under a skirt solve the sitting problem, and a higher-rise bottom closes a midriff gap.
1. Graphic Tee With Denim Shorts Outfit

A faded band tee with high-waisted light-wash denim shorts is the easiest outfit here, and fit is what makes it look chosen rather than grabbed. Go a size up in the tee at most; any bigger and it swallows the shorts and looks slept in. A loose front tuck shows the waistband. I'd check the shorts against your school's length rule before buying, since many cutoffs ride up once you sit. White crew socks, low-top sneakers and a canvas crossbody for your phone finish it.
2. Oversized Button-Up Shirt With Biker Shorts Outfit

An oversized striped button-up worn open over a white tank and black biker shorts handles the hot-hallway, cold-classroom problem better than almost anything. The shirt is your jacket. For summer school it also covers your arms and hips, which helps with dress codes, while the biker shorts stay cool underneath. Roll the sleeves once so it looks styled, not borrowed from a parent. Choose biker shorts in a thick, matte fabric, because thin shiny ones show every line. Chunky white sneakers and a belt bag for your water bottle finish it.
3. Cropped Cardigan With Tank And Wide-Leg Jeans Outfit

A light cropped cardigan over a white ribbed tank, with high-waisted wide-leg jeans, is a gentle outfit that suits presentation days. The cardigan is just warm enough for an air-conditioned room and small enough to stuff in a backpack outside. Because it's cropped, it should end right at the jeans' waistband; a gap there shows midriff, which many dress codes don't allow. A small front tuck of the tank keeps the proportions right. White sneakers or canvas lace-ups, a small pendant and a claw clip finish it.
4. Knit Sweater Vest With Pleated Skirt Outfit

A cream sweater vest over a white collared blouse with a navy pleated mini is preppy with a bookish edge. For summer I'd choose a cotton vest over wool, since cotton breathes better and won't itch against bare arms. A thin braided belt gives the waist some shape. Pleats in a polyester blend hold their crease longer, while an all-cotton skirt is cooler but needs pressing. White folded ankle socks, black loafers and a tan satchel finish it. If your school measures skirt length, swap in tailored shorts on the hottest days.
5. Striped Linen Shirt With Linen Shorts Outfit

A beige-and-white striped linen shirt tucked into pull-on linen shorts is one of the coolest ways to get through summer school days. Linen lets air through and dries fast, and a few creases are part of the look. Roll the sleeves below the elbow and leave the top button or two open. If you walk to school across wet grass, I'd pick woven slides over espadrilles, because jute soles soak up water and lose their shape. A straw tote and small gold hoops are enough. Check whether open-toe shoes are allowed at your school, since some ban them in labs.
6. Floral Midi Dress With Cropped Denim Jacket Outfit

A floral midi in soft blue and lavender with a cropped denim jacket is sweet without being fussy. The midi length passes any skirt rule, and the jacket covers bare shoulders when the AC kicks on or a teacher notices thin straps. White low-top sneakers are the walkable choice; flat sandals work if your school allows open toes. A small pendant and a woven crossbody won't compete with the print. Wear your hair in a low bun to keep your neck cool on the walk home.
7. Ribbed Tank With Cargo Pants Outfit

A fitted white ribbed tank tucked into olive drawstring cargo pants has a streetwear edge that holds up all day. The fabric matters more than the style: lightweight cotton twill cargos are fine in heat, but heavy canvas ones get sweaty fast. Go easy on the pockets, as stuffed side pockets bulge out at the thigh. Running shoes give support for long days on your feet, and a thin chain necklace with a couple of rings is plenty. If the tank straps are narrower than your school allows, keep an overshirt in your bag.
8. Ribbed Knit Matching Shorts Set Outfit

A sage ribbed knit set with a short-sleeve crewneck top and pull-on shorts feels like pajamas and looks dressed. Rib knit stretches and springs back, so it moves with you and keeps its shape through the day. The weak spot is the seat: rib knits can bag out after hours of sitting, so look for a cotton blend with a little elastane. White platform sneakers add contrast and a bit of height, and gold hoops with a chain bracelet keep it from looking lazy. A canvas tote and a messy bun finish it.
9. Baby Tee With Low-Rise Baggy Jeans Outfit

A white baby tee with a lettuce-edge neckline over light-wash low-rise baggy jeans is pure Y2K revival. The appeal is the contrast, snug on top and loose below. Low-rise is the tricky part for school, because the tee and jeans can leave a gap at the waist when you reach up or sit. I'd choose a baby tee that's a little longer than cropped, or a mid-rise baggy jean. A thin black belt, checkerboard slip-ons, a beaded bracelet stack and a hot pink or lime mini bag add the personality.
10. White Tube Top With Open Weave Shrug And Denim Shorts Outfit

A white tube top under an open-weave crochet shrug with distressed medium-wash denim shorts is the artsiest outfit here, and also the one most likely to break a dress code. Many schools ban tube tops outright, so keep the shrug on all day or swap the tube top for a fitted tank in the same color. Crochet snags on backpack zips, so carry a tote instead. Brown flat sandals, a few thin beaded necklaces, stacked silver rings and a tan hobo bag hold the boho mood together.
11. Polo Shirt With Pleated Tennis Skirt Outfit

A slim white polo with navy trim tucked into a navy pleated tennis skirt is sporty and neat, which is why it suits schools with stricter dress codes. Many tennis skirts come with built-in shorts, and I'd look for that; they make sitting on a classroom floor or climbing bus steps much easier. White ankle socks and court sneakers, a striped headband to keep hair back, a simple silver bracelet and a navy or white backpack finish it.
12. Printed Co-Ord Skirt Set Outfit

A terracotta and cream printed co-ord with a short-sleeve cropped top and an A-line mini takes two minutes to put on, which is its real value on mornings when you overslept. Rayon sets drape softly and stay cool, but they shrink in a warm wash, so wash cold and hang to dry. The crop and the mini are the two pieces to check against school rules; the top should still meet the skirt when you lift your arms. Neutral slides or white sneakers, small gold button earrings and a rattan crossbody suit the print.
13. Crochet Trim Cami With Linen Trousers Outfit

A cream camisole with scalloped crochet trim, tucked into sand-colored wide-leg linen trousers, is the most grown-up outfit on this list and suits older teens. The trousers cover the whole leg and still feel cool. Cami straps are usually thin, so if your school has a strap rule, wear an open linen shirt over it. A thin brown belt marks the waist. Tan woven slides or low mules, a few fine gold necklaces, tortoiseshell sunglasses and a beige tote finish it. Have the trousers hemmed so they don't drag, because wide linen hems fray quickly on pavement.
14. Cropped Hoodie With High-Waisted Joggers Outfit

A heather grey cropped hoodie with matching high-waisted joggers is the outfit for a freezing classroom. Summer versions in French terry are much lighter than winter fleece, and the looped inside of the fabric soaks up sweat. The short hoodie balances the relaxed jogger silhouette so you aren't lost in fabric. White low-profile sneakers, a low ponytail, small studs and a crossbody belt bag make it look planned. On the hot walk home, tie the hoodie around your waist.
15. Cotton Sundress With Espadrille Sandals Outfit

A white cotton eyelet sundress with a square neckline and thin straps is light and cool for an outdoor lunch. Eyelet is cotton with small embroidered holes, so it breathes well, but those holes can show what's underneath; check that it's lined. The thin straps are the dress-code risk, so keep a light cardigan or denim jacket handy. Tan espadrilles, a ribbon in a low ponytail, a straw crossbody and pearl drop earrings finish it. I'd save it for a day you're heading somewhere nice after class.
16. Striped Shirt Over Biker Shorts Outfit

An oversized navy-and-white striped shirt worn as a dress over black biker shorts is a cool, covered option that plenty of teen girls already own the pieces for. Length is everything: the shirt should cover the shorts almost completely, with just a few inches showing at the hem. Raise your arms in the mirror, and if the hem jumps too high, wear it as a shirt over longer shorts instead. Roll the sleeves below the elbow. White tube socks with slides or sneakers, a black cap and a nylon shoulder bag finish it.
17. Belted Shorts With Blouse Outfit

Sage green tailored belted paperbag shorts with a white puff-sleeve blouse look far more polished than shorts and a tee. The gathered waist and fabric belt give the shorts structure, and the blouse tucks in cleanly. A paperbag waist already adds volume at the middle, so tuck neatly and skip any bulky top. The puff sleeves cover the shoulders, which helps if you prefer modest dressing. Nude flat sandals or white ballet flats, pearl studs, a thin gold bracelet and a soft crossbody finish it. Tailored shorts also tend to pass length rules where cutoffs don't.
18. Square Neck Bodysuit With Trouser Shorts Outfit

A white square-neck bodysuit tucked into high-waisted black trouser shorts gives a sleek line that stays put all day, since a bodysuit can't come untucked. The downside is the snap closure, which makes bathroom breaks slower; a fitted tank is a fine stand-in. Trouser shorts look more polished than denim cutoffs and usually come in a longer, school-friendly length. Black slides, a thin chain belt, a gold necklace and a structured black tote or backpack keep it minimal.
19. Denim Midi Skirt With Fitted Tank Outfit

A light-wash denim midi with a front slit and a dusty pink ribbed tank is a casual skirt outfit that's easy to move in. The slit is what lets you walk and take stairs, but check where it ends, because a slit reaching mid-thigh can break a length rule once you sit. Denim midis are heavier than cotton skirts, so this one suits warm days rather than scorching ones. White canvas sneakers, a pendant, colorful beaded bracelets, a cream tote and a pink scrunchie on a high ponytail finish it.
20. Tie-Front White Tee With Striped Shorts Outfit

A white cotton tee with a small tie at the hem over high-waisted blue-and-white striped pull-on shorts is cheerful and quick. Tie the knot at the side rather than dead center so it doesn't lift the tee above your waistband. The stripes look crisp and nautical without any effort from you. Navy espadrille slip-ons tie the colors together, and a red canvas tote with gold studs adds a pop. Keep your hair up off your neck on hot walks.
Turning Twenty Outfits Into One Week of Class
You don't need twenty outfits for a few weeks of summer school. Many of the looks above share the same handful of pieces, so you can build a rotation from what you already own and only buy to fill real gaps.
The pieces that keep coming back
- Light-wash high-waisted denim shorts
- Black biker shorts in a thick, matte fabric
- A white ribbed tank and a plain white tee
- One oversized button-up shirt, striped or plain
- A light cardigan or cropped denim jacket for the cold classroom
- White sneakers you can walk in all day
Those six cover a good share of this list. Add one dress and one skirt or pair of trousers you really like, and you have five different school days. Wash biker shorts and ribbed knits cold and hang them to dry, since dryer heat wears out the stretch that keeps them in shape.
Cool on the Walk, Warm in Class, Inside the Rules
Summer school clothes have three jobs: keep you cool outside, warm enough in a chilled classroom, and inside the dress code. Breathable cotton, linen and light knits handle the heat, and one layer you can carry, such as a shirt, cardigan or jacket, handles the cold room. Pick the outfits here that match your style, borrow pieces between them, and you'll have a week of class outfits mostly from what's already in your closet.
