While airport fashion and red carpet glam steal the spotlight in K-pop, dance practice outfits remain a hidden gem of idol style — blending comfort, performance readiness, and unexpected flair. But behind those seemingly casual sweats and oversized tees lies a smart mix of aesthetic and functionality, often discussed passionately by fans and dancers alike.
In this article, we’ll explore what makes a great K-pop dance practice outfit, why idols sometimes wear surprisingly heavy layers, and which fits are fan favorites.

1.Why Do Idols Wear Heavy Clothes in Dance Practices?
A Reddit post on r/kpophelp raised a surprisingly common question:
"Why are K-pop idols wearing hoodies, sweatpants, and even jeans during intense dance practices? Don’t they get hot?"
Here’s what real dancers and fans had to say:
Idols often rehearse in velvet, jacquard, and other heavy materials on stage under intense lighting. By practicing inlayers, they acclimate their bodies to the heat, weight, and movement restrictions of stage outfits — reducing the chance of overheating or discomfort during live performances.
Dance studios are often air-conditioned and cold. Professional dancers emphasize the importance of keeping muscles warm to avoid stiffness and injury. That’s why layering hoodies, track jackets, or even leg warmers is a common habit, especially during warm-ups and breaks between takes.
- “Ballet dancers do the same,” one Redditor noted. “You need warmth to keep muscles flexible.”
Not all practice videos are raw behind-the-scenes content. Some are designed for fans and intentionally stylish, blending choreo footage with brand deals and visual appeal. This explains the occasional use of jeans, accessories, or full makeup — particularly in sponsored dance content.
2.Style Trends in Dance Practice Outfits
Across Reddit and fan communities, users repeatedly highlight certain styling elements that make dance practice outfits memorable:
| Style Trend | Description |
|---|---|
| Oversized Tops | T-shirts, hoodies, and sweaters that add movement and drama. |
| Baggy Bottoms | Sweatpants, joggers, or cargo pants are comfy and dynamic. |
| Crop Tops + Joggers | A favorite combo for its athletic-meets-feminine look. |
| Biker Shorts | Once divisive, now embraced — especially by ITZY’s Ryujin. |
| Layered Looks | Cardigans, track jackets, or double-layered tops for depth. |
| All-Black or Monochrome | Clean, cohesive, and visually striking on camera. |
Dance practice fashion in K-pop isn’t just about comfort — it’s also a subtle form of self-expression. Over time, fans have picked up on clear fashion patterns that dominate practice rooms. From oversized hoodies to retro fits, here are some standout styles that continue to shape how idols show up for rehearsal.
1. Oversized Tops and Sweats: The “Training Day” Look
One of the most iconic combos is a loose-fitting t-shirt or hoodie paired with joggers or sweatpants. It’s practical, breathable, and ideal for movement. BTS’s “Run BTS” practice video showcases Jungkook in a full black tracksuit — both sleek and functional. Similarly, SHINee’s Taemin in Lucifer wore a now-infamous striped long-sleeve shirt that became meme-worthy for its camera-distorting moiré effect.
2. Crop Tops and High-Waisted Bottoms: Sporty Meets Chic
Female idols often gravitate toward form-fitting crop tops paired with loose or high-waisted bottoms — a look that balances femininity with athletic ease. BLACKPINK’s Rosé nailed this in both “Lovesick Girls” and “How You Like That” practice videos, wearing off-shoulder tops layered with sports bras and soft cardigans. The looks were casual, yet felt stylish and powerful.
3. Monochrome or All-Black: Simplicity That Pops
All-black outfits aren’t just sleek — they’re practical. They help highlight choreography without visual distractions. In NCT Taeyong’s “Make a Wish” dance practice, his gray long-sleeve shirt and blue jeans looked effortlessly stylish while keeping the focus on the moves. Minimalism really works when done right.
4. Retro and Statement Mixes: Personality on Display
Some idols take a more expressive route, leaning into retro aesthetics or bold combinations. GFRIEND’s Yuju delivered major retro vibes in the “MAGO” practice video, while Sunmi channeled disco energy in “When We Disco.” These looks go beyond function — they build an atmosphere.
5. Biker Shorts: From Controversial to Cool
Once met with mixed reactions, biker shorts have now become a regular feature, especially in girl group practices. ITZY’s Ryujin wears them confidently, pairing them with oversized t-shirts or sporty jackets. One Redditor noted: “I didn’t like them at first, but they grew on me — they actually look cool in motion.”
6. Mismatched Chaos: The Power of Uncoordinated Looks
Sometimes, the charm lies in the lack of coordination. BTS’s “Go Go,” “Baepsae,” and “Airplane Pt.2” dance practices are fan favorites because the members wear whatever they want — pajamas, suits, or casual streetwear. There’s something authentic about the randomness, like you’re watching them in their real element.
- "I prefer when it looks like they just turned on a camera on a regular day,” one fan wrote. “Coordinated outfits feel staged.”
3.Fan-Favorite Dance Practice Outfits
Over the years, several idols and groups have served iconic looks during dance practice. Here are a few outfits that left lasting impressions:
In “Lovesick Girls” and “How You Like That” practices, Rosé wore off-shoulder tops with layered sports bras and a cardigan — blending elegance with edge.
- “The silhouette was so unique. The cardigan? Chef’s kiss.”
Lucifer
His striped shirt in the Lucifer dance practice is notorious for causing camera moiré — and fans love it.
- “That shirt lives in my head rent-free.”
His sleek track suit in Run BTS is widely praised for its clean fit and comfortable vibe.
- “I wanted that exact outfit so bad.”
In Make a Wish, Taeyong wore blue jeans and a gray Zegna long-sleeve shirt — minimalist but effortlessly stylish.
- “Simple, but he looked so good in it.”
✨ Le Sserafim - Easy Era
Their “cool girl” aesthetic became a fan-favorite, with Saki’s outfit standing out for its fashion-forward edge.
- “Every outfit in that video was perfection.”
4. The Dual Nature of Practice Outfits: Realism Meets Branding
At first glance, K-pop dance practice videos feel raw and unfiltered — just idols dancing in a mirrored studio in comfy clothes. But over the years, fans have noticed a shift: what once seemed candid has increasingly become a curated visual experience. Today’s practice outfits often walk the line between realism and brand-conscious presentation.
In the early 2010s, dance practice videos were rarely uploaded. When they were, they looked simple and unpolished — SHINee’s “Sherlock” practice famously used a toilet paper roll as a stage marker. But with the rise of YouTube and global fandoms, these behind-the-scenes clips evolved into a genre of content on their own, where styling became just as important as the choreography.
- “Dance practices used to feel like a candid peek into idol life,” one Reddit user noted, “but now some feel more like a fashion editorial.”
As the reach of K-pop grew, so did brand interest. Many recent practice videos feature sponsored clothing and footwear, often from global fashion houses. For example:
- NMIXX’s “See That?” dance practice featured custom Golden Goose sneakers, with the members actively highlighting their designs on camera.
- Members of Le Sserafim, NewJeans, and Blackpink have been seen wearing Celine, Adidas, Chanel, and Nike, even during casual practice clips.
These partnerships are strategic. Dance practice videos garner millions of views — a perfect runway for product placement that feels organic, especially when idols are seen “working hard” in those brands.
There’s also been debate around the polished makeup and hairstyling some idols wear in dance practice videos. While some fans enjoy the glam, others miss the bare-faced realism of earlier content.
- “It’s weird when they look more ready for a photoshoot than an actual dance rehearsal,” one fan wrote. “I liked it better when they showed up in bare skin and messy ponytails.”
Still, there’s value in presentation. Companies want to protect the idol’s image — even casual content must align with the group’s overall aesthetic. This tension between relatability and perfectionism is part of the K-pop package.
⚖️ Balancing Authenticity and Visual Identity
Not all dance practices are stylized — many still retain a natural vibe. BTS’s “Run BTS” and “Go Go” videos are often praised for their relaxed, chaotic outfits. Similarly, groups like aespa and Mamamoo are frequently mentioned for showing up in minimal makeup and realistic training gear.
The balance varies by group and era. But at its core, this dual nature reflects a key truth about modern K-pop: everything is performance, even the “behind-the-scenes.”
Final Thoughts
K-pop dance practice outfits are more than just comfy clothes — they’re a reflection of training discipline, personal style, and visual storytelling. Whether it’s oversized sweats or trendsetting biker shorts, these looks resonate with fans because they blur the line between effort and ease, polish and personality.
From Taemin’s glitchy shirt to Rosé’s off-shoulder tops, K-pop idols have turned even their rehearsals into a runway.
