If you’re anything like me, you’ve probably spent hours watching K-pop practice videos, secretly wishing you were part of the K-pop trainee life. I’m obsessed with how these trainees look so cool and stylish, even when they’re just sweating it out in the studio.
There’s something so magnetic about their practice outfits, comfortable enough for long rehearsals but still fashionable enough for fan cams. So if you’re looking to recreate that K-pop training outfit vibe, you’re in the right place.
Here are 15 trainee-approved outfit ideas that’ll help you look the part, from studio practice to mirror selfies in your room.
1: Oversized Hoodie
Oversized hoodies are hands down the most iconic part of any K-pop trainee outfit. You see them everywhere: on trainees walking into dance studios, warming up for vocal lessons, or just chilling backstage.
They give off the perfect “I’m busy chasing my dreams” energy while keeping things comfy and laid-back.
I have this one hoodie that’s three sizes too big, and it’s honestly the comfiest thing I own. It hides sweat stains, lets me move freely, and makes me feel like I’m one rehearsal away from debut.
Match it with fitted leggings or biker shorts, and you’re good to go.
2: Black Leggings
If K-pop outfits had a dress code, black leggings would be top of the list. These babies are stretchy, breathable, and hug your body just right.
I can dance, jump, stretch, and even collapse dramatically on the floor in them without worrying about anything.
I like to pair mine with a cropped top or oversized tee, depending on my mood.
The best part is that they go with literally everything and make you feel super sleek, even if your dance moves are still in the awkward but trying phase.
3: Crop Tops
Crop tops are a bold but popular choice in the K-pop training outfit world. They’re breathable and allow for maximum movement, especially during long, sweaty dance practices.
Plus, they give off serious confident trainee vibes.
I remember wearing my first crop top to dance class and feeling like I just stepped into a YG practice room.
If you’re not totally comfortable showing skin, throw on a flannel over it or pair it with high-waisted bottoms. Trust me, it still looks cool.
4: Sports Bras
When things get intense and, let’s be real, Kpop Trainee Life is nothing if not intense; sports bras come in clutch.
They offer full support during high-energy choreography sessions and still look great on their own.A lot of trainees wear them solo or layered under mesh tops.
I personally love ones in bold colors or interesting textures.
They add just enough flair to stand out but still keep you comfortable and grounded during hours of practice.
5: Bucket Hats
Ever notice how so many trainees wear bucket hats during dance practice? It’s not just a style thing, although they absolutely nail the look.
These hats help keep sweat and hair out of your face while adding that mysterious too-cool-for-you vibe that defines the K-Pop trainee outfits aesthetic.
I have one in black and another in pastel pink. They make me feel like a backup dancer in a BTS rehearsal video.
Add some hoop earrings, and you’ve got a full look.
6: Baseball Caps
Baseball caps are another fan favorite in K-pop outfit practice. They keep your hair pulled back, help you focus, and instantly make your outfit look sharper.
I throw one on when I haven’t washed my hair, and suddenly I look purposefully messy instead of just messy. Plus, they go with pretty much any outfit.
I love ones with cute logos or embroidered quotes. Very trainee-core.
7: Flannel Shirts
Flannel shirts tied around the waist scream cool trainee on break. They’re stylish, practical, and give your outfit an instant edge.
I like to wear mine over a tank top or cropped tee, and if I get too hot, I just wrap it around my waist like the idols do.
Flannels are a huge part of the street-meets-studio vibe in Kpop Trainee Life.
Pick a fun color or a classic plaid, and you’ll look like you stepped right out of a fan edit.
8: Zip-Up Jackets
Need to warm up before rehearsal? A zip-up jacket is your new best friend.
They’re lightweight, breathable, and perfect for layering during early morning practices or chilly studios.
I usually keep one in my dance bag because it goes with every outfit.
They also make you look a bit more official, like you’re on your way to an actual showcase.
9: Jogger Pants
Not feeling leggings? No worries.
Joggers are super comfy, loose-fitting, and totally in style with K-pop training outfit fashion.They allow full movement and can be dressed up or down.
I like pairing mine with a tight top to balance the fit and some chunky sneakers for that full trainee aesthetic.
10: Graphic Tees
If you want to show off a little personality, graphic tees are the way to go. Think oversized shirts with bold prints, funny phrases, or subtle K-pop references.
They’re perfect for long practices and casual hangouts after. I wear mine tucked into leggings or tied at the waist.
It’s a simple look, but it fits the relaxed, fun style you see in practice outfits all over Pinterest.
11: Matching Sets
Want to look like you walked straight out of a girl group’s training video? Matching workout sets are the answer.
These usually come as leggings and crop top combos and give a super sleek put-together look.
I love them in pastel tones or monochrome colors.
They boost my confidence instantly and make me feel like I’m part of a trainee group even when I’m just dancing at home.
12: Knee-High Socks
Knee-high socks are cute, comfy, and totally K-pop-coded. They add a schoolgirl vibe when paired with shorts or skirts and keep your legs warm in cold practice rooms.
I have them in black, white, and even neon green.
They’re such a fun way to add a little flair to your outfit and look great in K-pop outfits in practice mirror selfies.
13: Arm Warmers
For an edgy twist, arm warmers are making a comeback in K-Pop trainee outfits. You’ll see them on streetwear-inspired trainers who want to stand out.
They add a futuristic vibe to even the simplest outfit. I like wearing them with sleeveless tops to create a contrast.
Bonus points if they have thumbholes because it just feels cooler.
14: Face Masks
Last but not least, face masks have become part of the trainee look. Not only are they protective, but they also give off serious idol-on-the-go energy.
Many trainees wear them to stay focused or hide that no-makeup look during late-night practices.
I keep a stash of cute and simple ones in my bag. They add mystery and polish to any K-pop training outfit combo.
