1. Baggy Jeans + Oversized Sweatshirt

Loose, wide-leg jeans paired with an oversized sweatshirt are a back-to-school staple. This combo gives you a relaxed, street-style vibe while keeping you fully covered and comfortable. Choose neutral shades for a minimal aesthetic, or go bold with graphic sweatshirts for personality. Sneakers tie the look together perfectly.
2. Long Cardigan + Loose Trousers
A long, flowy cardigan adds instant elegance to any outfit. Pair it with a plain t-shirt and wide-leg trousers for a modest yet fashionable classroom look. Cardigans also work great for layering in cold classrooms, and they give you endless styling flexibility.
3. Plaid Maxi Skirt + Knit Sweater
Plaid skirts are a huge trend, but instead of going short, go modest with a plaid maxi skirt. Pair it with a chunky knit sweater for a cozy preppy look. You can also add loafers or ankle boots for a polished vibe. This outfit balances Pinterest-worthy style with complete coverage.
4. Denim Jacket + Long Dress
Take your favorite long dress (floral or solid) and throw on a denim jacket for instant back-to-school chic. This look transitions perfectly from summer to fall. It’s easy to style, modest, and gives you that effortless “put together” vibe without trying too hard.
5. Athleisure: Joggers + Oversized Hoodie
Athleisure doesn’t mean tight clothing—you can go modest with loose joggers and an oversized hoodie. It’s the ultimate comfort outfit for busy school days. Stick with neutral tones for a clean aesthetic, or mix in fun pastel hoodies for a playful twist.
6. Long Tunic Top + Straight-Leg Jeans
Tunic tops are modest fashion heroes. Pair them with straight-leg jeans for a look that’s both trendy and appropriate for school. You can wear this with loafers, sneakers, or even boots depending on your style. It’s simple, practical, and stylish all at once.
7. Overall Jumpsuit + T-Shirt
Instead of short overall dresses, choose denim overalls or a wide-leg jumpsuit layered over a plain t-shirt. This look is modest, playful, and very teen-friendly. It’s especially great for days you want something different from jeans but still casual.
8. Oversized Flannel + Baggy Pants
The flannel trend is timeless and perfect for modest dressing. An oversized flannel shirt with loose black pants or baggy jeans gives off relaxed “cool girl” energy. Pair with sneakers or combat boots for extra edge.
9. Pleated Long Skirt + Polo Shirt
Instead of the tennis mini skirt trend, go for a pleated long skirt. Style it with a polo shirt or button-down for a sporty-preppy aesthetic that’s still modest. Add chunky sneakers to keep it modern and teen-approved.
10. Bomber Jacket + Relaxed Jeans
Bomber jackets never go out of style. Layer one over an oversized tee with relaxed-fit jeans for a modest, streetwear-inspired outfit. Perfect for when you want to look confident without being flashy.
11. Maxi Skirt + Baggy Graphic Sweatshirt
For a trendy yet modest vibe, pair a flowy maxi skirt with a baggy graphic sweatshirt. This combo is comfortable, Pinterest-worthy, and unique enough to stand out. Add high-top sneakers to complete the look.
