29 Aesthetic Halloween Costumes for Teens That Are Fun, Stylish, and Totally Instagram-Worthy

Halloween has always been more than just candy and haunted houses. For teens, it’s a chance to show personality, creativity, and style in a way that feels effortless but still eye-catching. The rise of social media has only made it more exciting, with many teens now hunting for aesthetic Halloween costumes that not only work for parties but also look amazing in photos.

Think of it as mixing fashion with fun. It’s not just about being scary anymore—it’s about curating a vibe. Whether you lean toward vintage, dreamy, spooky, or minimalist styles, there’s a costume that fits your mood and aesthetic. The best part? Many of these ideas can be created with clothes you already own, plus a few clever accessories.

Below, you’ll find 29 aesthetic Halloween costume ideas for teens. Each one is explained in detail so you can see how to pull it off, what makes it special, and how it can reflect your unique personality.

1. The Cottagecore Witch

Cottagecore already has that cozy, nature-filled vibe, so turning it into a witch costume feels natural. Imagine a flowy dress, lace-up boots, and a wide-brim hat decorated with fake flowers. Add a wicker basket filled with faux herbs, and you’ll look like a woodland witch straight out of a fairytale. This costume is aesthetic because it mixes earthy tones with a touch of mysticism, perfect for teens who want charm instead of fright.

2. The Vintage Ghost

Forget the plain white sheet. Aesthetic ghosts are draped in lace curtains, silky fabrics, or thrifted vintage sheets with embroidered edges. Pair it with retro sunglasses and platform sneakers, and suddenly, you’re both spooky and stylish. Teens love this because it feels ironic, yet it looks incredible on Instagram feeds.

3. The Dark Academia Student

Think plaid skirts, long coats, turtlenecks, and a leather satchel. This aesthetic plays into moody lighting and candlelit libraries, making it perfect for Halloween. Carry an old book, scribble fake Latin notes, and you’ve got the ultimate mysterious academic vibe. It’s subtle but powerful—ideal for teens who want to look put-together while staying on theme.

4. The ’90s Vampire

Instead of the usual cape and fangs, go retro. Wear thrifted leather jackets, high-waisted jeans, and dark lipstick. Add fake fangs for that extra edge. This look is both nostalgic and effortlessly aesthetic, especially since ’90s fashion has made a huge comeback among teens.

5. The Space Fairy

Imagine combining celestial and fantasy vibes—glittery makeup, silver wings, and holographic skirts. A space fairy is the perfect costume for teens who love sparkle and want something unique. Add star-shaped hair clips or glow-in-the-dark stickers, and you’re basically glowing at night.

6. The Retro Prom Queen Zombie

Dig up an old prom dress (or thrift one), add a sash, and then distress it with fake blood or torn fabric. Curl your hair, wear a tiara, and smudge your makeup for that eerie-but-pretty zombie aesthetic. Teens often love this because it’s both scary and glamorous.

7. The Clueless-Inspired Cher

Plaid skirt suits, knee-high socks, and a mini backpack scream Clueless. This is the ultimate ’90s teen girl aesthetic, and it works perfectly as a costume. If you want to add a Halloween twist, you can carry a fake cell phone with a spooky cracked screen look.

8. The Angel in Streetwear

Instead of the classic flowing gown, wear a monochrome outfit like all-white jeans, a crop top, and sneakers. Add fluffy angel wings and a halo, and suddenly you’re a modern take on the angel aesthetic. This idea resonates with teens who want comfort without losing the Instagram-worthy vibe.

9. The Pastel Goth

This is the best of both worlds—soft pinks and purples mixed with dark chokers and combat boots. A pastel goth look feels unique, playful, and aesthetic without being too over-the-top. Throw in some fun makeup with glitter tears or star stickers, and you’ll stand out.

10. The Mermaidcore Look

Mermaidcore is already trending, so why not bring it to Halloween? Use iridescent fabrics, seashell accessories, and blue or green glitter makeup. You don’t even need a full tail—just a shiny skirt or sequin leggings. Teens love this because it feels whimsical and otherworldly.

11. The Wednesday Addams Aesthetic

Wednesday Addams has become a teen fashion icon thanks to Netflix. A collared black dress, braids, and a deadpan expression are all you need. For a Halloween twist, you can add ghostly makeup or carry a gothic accessory like a fake raven.

12. The Glitter Demon

Think horns, sparkly makeup, and edgy clothing. A glitter demon balances spooky with glam, making it a perfect teen costume. Black jeans with a glitter top and bold eyeliner can create the look without needing a full-on costume purchase.

13. The Vintage Hollywood Starlet

Go glam with a silk slip dress, long gloves, and soft curls. Carry a feather boa or faux fur stole for added drama. Teens who want elegance and aesthetic vibes will love this because it looks chic in photos while still being on theme for Halloween.

14. The Cyberpunk Hacker

Neon makeup, oversized jackets, and reflective sunglasses define this costume. Add some glow stick accessories, and you’re ready. Teens who love tech or futuristic aesthetics will find this costume both fun and stylish.

15. The Y2K Pop Star

Shiny pants, crop tops, butterfly clips, and tinted sunglasses scream early 2000s. Add a toy microphone and a little glitter, and you’re basically Britney Spears or Christina Aguilera during the Y2K era. Teens love this throwback aesthetic.

16. The Pumpkin Queen

An orange dress, black boots, and pumpkin-inspired accessories make this look adorable and spooky. Paint your nails orange and black for that extra touch. It’s a simple but aesthetic costume idea that works well for teens who want festive vibes.

17. The Gothic Ballerina

Take a tutu, add ripped tights, and dark eye makeup. Suddenly, you’ve turned ballet into a hauntingly beautiful costume. Teens who like dance or want a mix of grace and darkness often choose this look.

18. The Sun and Moon Duo (Solo Version Works Too)

Wear gold for the sun or silver and navy for the moon. Add face glitter shaped like stars or rays. This costume feels celestial and aesthetic, especially with simple DIY accessories like painted cardboard crowns.

19. The Haunted Doll

A frilly dress, rosy cheeks, and cracked doll makeup make this costume chilling yet aesthetic. Carry a small toy or parasol for extra detail. Teens love this because it mixes innocence with creepiness in a stylish way.

20. The Skater Ghoul

Pair your regular skater outfit—oversized hoodie, sneakers, and cap—with pale makeup and dark under-eyes. Suddenly, you’re a ghostly skater. It’s low-effort but high-aesthetic, especially for teens who already dress this way.

21. The Greek Goddess

Drape a white sheet or dress with gold accessories, and you’ve got a timeless look. Add some golden hairpieces or faux ivy, and it feels instantly Instagram-worthy. Teens who love mythology will enjoy embodying this aesthetic costume.

22. The Dark Fairy

Unlike the space fairy, the dark fairy goes gothic—black wings, ripped tights, and deep purple makeup. It’s aesthetic because it balances beauty with spookiness. Teens love this one because it feels powerful and mysterious.

23. The Soft Girl Ghost

Take the pastel soft-girl aesthetic and merge it with ghostly white. Oversized pastel sweaters, pleated skirts, and sheer fabrics can create a dreamy haunted vibe. Teens who want something cute but Halloween-appropriate adore this idea.

24. The Grunge Rockstar

Ripped jeans, oversized band tees, and heavy eyeliner—add a fake guitar, and you’re ready to rock. This costume is especially aesthetic for teens into alternative fashion or music.

25. The Royal Vampire

Forget basic vampire looks. Add a velvet cloak, jeweled crown, and ornate accessories. You’ll look like vampire royalty straight from a fantasy novel. Teens who want a mix of elegance and horror love this aesthetic.

26. The Alien in Disguise

Metallic pants, colorful wigs, and funky sunglasses make for a fun alien aesthetic. Carry a toy ray gun for laughs. Teens love this because it’s quirky, colorful, and not your typical scary costume.

27. The Whimsical Clown

Instead of scary clowns, go whimsical. Use pastel colors, oversized bows, and glitter makeup. Teens who love aesthetic twists enjoy this look because it’s playful without being terrifying.

28. The Retro Film Noir Detective

Think trench coat, fedora, and dramatic eyeliner. Add a magnifying glass for fun. Teens who want a moody, aesthetic costume with vintage vibes will love this style.

29. The E-Girl Vampire

Take the classic E-girl look—plaid skirt, striped shirt, chunky boots—and add vampire makeup with fangs. It’s edgy, trendy, and aesthetic, making it one of the most teen-friendly Halloween costumes this year.
