Forget the days when K-pop idols treated Incheon International Airport like a high-stakes red carpet. You remember the era—restrictive skinny jeans, towering heels, and high-glamour ensembles that looked uncomfortable for a five-minute car ride, let alone a twelve-hour flight to Paris. But as we head through 2025 and into 2026, the “Incheon Runway” has seen a total vibe shift. The “trying too hard” look is dead. In its place? A curated, effortless aesthetic where K-pop idol oversized airport fashion is the ultimate power move.
Central to this fashion evolution is the rising “Sonminsu” (손민수) phenomenon. In K-fandom culture, to “Sonminsu” someone means to mirror their style or hunt down the exact items they’re wearing. By 2025, fans aren’t just hitting the “like” button on Instagram. They are actively rebuilding their wardrobes to match these full-baggy coordinates. We saw this peak during the 2025 Asia Artist Awards (AAA) departures. The terminal looked like a real-time catalog for the “slouchy” aesthetic, proving that being comfy and being a fashion icon are now the same thing.
The Dual Strategy: Paparazzi Shield vs. Luxury Canvas
Why has the oversized fit become the industry standard? For idols, these “comfy luxury” looks serve two very different purposes. First, there’s the practical side. Baggy hoodies and wide-leg pants act as a “paparazzi shield.” When you’re dealing with a wall of cameras after a grueling world tour, a massive hood and an oversized silhouette offer a literal sanctuary. It’s about privacy. It’s about having a buffer between yourself and the lens when you’re dealing with travel fatigue.
But don’t be fooled—there’s a strategic commercial angle here too. High-end houses like Fendi, Burberry, and Celine have noticed that Gen Z isn’t buying formal wear. They want streetwear-influenced silhouettes. These oversized pieces provide a much larger canvas for brand logos and unique textures. They stand out more in low-res phone previews and fan-taken previews.
And then there’s the move toward gender-neutral K-pop clothes. In the 2026 season, the lines have blurred almost entirely. Groups like NewJeans and Stray Kids are frequently spotted in the same non-binary silhouettes. They’re ignoring traditional body lines to prioritize personal “swag” and a rebellious energy. It’s a “vibe over fit” philosophy that has completely redefined how we view idol styling.
Stray Kids’ Bang Chan: The Fendi Global Ambassador
When Bang Chan arrived at Incheon for the AAA 2025 departures, he basically redefined “elevated carryall” style. The Stray Kids leader didn’t go for anything flashy. Instead, he wore a sophisticated beige gabardine jacket that looked effortlessly expensive. He layered it over a crisp white Fendi Roma jersey tank. It was the perfect mix of boyish charm and high-fashion luxury. By pairing his oversized outerwear with heavy platform boots, he showed fans how a “baggy” look can still feel structured and high-end.
IU: The Queen of the Leather Bomber
IU has always had a knack for making casual looks chic, but her recent airport appearances have taken an edgy turn. She’s been leaning into the “comfy luxury” standard by opting for oversized black leather bomber jackets. Paired with loose-fitting charcoal trousers, the look is both rebellious and protective. Fans were quick to “Sonminsu” the jacket, causing a massive surge in demand for vintage-style leather pieces that offer that same “borrowed from the boys” feel.
aespa’s Ningning: Rebellious Slouchy Aesthetic
Ningning is currently the face of the “scuffed” streetwear vibe. Recently, she was seen in a customized scarlet red sweater paired with black shorts. Her look is the textbook definition of the “rebellious slouchy” trend. It ignores gender lines and emphasizes movement. When she walks through the terminal, the clothes move with her, creating a silhouette that is all about “swag” rather than showing off a specific form. It’s a bold departure from the hyper-feminine looks of the past.
Stray Kids’ Seungmin: Burberry’s Baggy Vision
Flying out for London Fashion Week, Seungmin gave us a masterclass in monochrome. He wore a navy knitted sweater featuring an intricate knight design, but the real star was the pants. He opted for surprisingly baggy navy leather trousers. This outfit proved a major point: the baggy aesthetic isn’t just for hoodies and sweats. It can be translated into high-end editorial looks if you play with the right materials.
NewJeans’ Hanni: The Ultimate Sonminsu Hoodie
Hanni is the master of the “tiny idol in big clothes” aesthetic. She recently went viral for an oversized cream-colored zip-up hoodie that completely swallowed her frame. Paired with wide-leg sweats, it looked like the ultimate cozy travel fit. Naturally, this sparked a “Get the Look” TikTok trend immediately. The hoodie became one of the most sought-after “Sonminsu items” of the year because it felt attainable and relatable, yet undeniably cool.
BLACKPINK’s Jennie: The Y2K Baggy Hybrid
You can’t talk about trends without Jennie’s airport fashion. She was recently spotted bridging the gap between Y2K nostalgia and modern utilitarian chic. She balanced out exaggeratedly wide charcoal cargo pants with a black cropped hoodie. This “baggy hybrid” look is perfect for fans who want to try the trend without feeling totally overwhelmed by fabric. It keeps a hint of a traditional silhouette while leaning into the volume of 2026 fashion.
NCT’s Taeyong: The Avant-Garde Baggy Master
Taeyong is the one who started the “Baggy Jeans” movement, and he’s still leading it. He arrived at the airport recently in a massive black leather jacket over an oversized black baggy jeans. Taeyong’s style is always a bit more avant-garde than his peers. He uses extreme volume as a shield, creating a profile that looks like it belongs on a runway in Milan rather than an airport terminal. He’s not just wearing clothes; he’s wearing a silhouette.
BTS’s Jungkook: All-Black Calvin Klein Oversized
In his first major public appearance post-service, Jungkook proved that some things never change—like his love for a good oversized fit. He solidified the “minimalist baggy” trend with an all-black Calvin Klein ensemble. It featured an oversized denim jacket and matching wide-leg jeans. It was a powerful reminder that you don’t need loud colors to make an impact. Sometimes, a monochromatic, well-cut oversized fit says everything it needs to.
aespa’s Karina: The “Wide Jeans” Blueprint
Karina often goes for a more “wearable” version of the trend. Her blueprint? A fitted white tee paired with massive, light-wash blue wide-leg denim. This “minimalist chic” approach is what most fans end up replicating for their daily lives. It’s the quintessential individualized expression of the season—balancing the baggy trend with pieces that feel accessible.
IVE’s Wonyoung: Miu Miu’s Baggy Cashmere
Wonyoung is usually known for her “doll-like” and polished aesthetic. That’s why it was such a shock to see her adopt the “baggy shield” for a recent long-haul flight. She stepped out in a “slouchy” off white cashmere oversized jacket with corduroy trousers from Miu Miu. It was a clear signal that even the most feminine fashion icons are prioritizing comfort and privacy for their 2026 schedules.
ATEEZ’s Hongjoong: Balmain Cardigan Volume
As the “Captain” of fashion, Hongjoong never plays it safe. He recently opted for a black oversized lace knit cardigan with matching “flared” pants. His look showed how the rebellious slouchy aesthetic works for high-energy performers. It gives him room to move and breathe while maintaining that high-fashion edge. It’s a look that reflects his personality—bold, loud, and completely original.
LE SSERAFIM’s Chaewon: The Oversized Vintage Look
Chaewon has been leaning into the “off-duty idol” vibe. She was recently seen in a StandAloné Raglan Fade Out sweatshirt and Dunst Oversized Vintage Leather jacket that fell all the way to her mid-thigh. Paired with baggy light blue pants, it was the perfect look for a 10-hour flight to a global award show. It’s a look that prioritizes the human element of being an idol—sometimes, you just want to be cozy while looking like a million bucks.
NewJeans’ Danielle: Celine’s Oversized Sophistication
Danielle arrived at Incheon in a black and gold Celine varsity jacket that looked at least three sizes too big. She paired it with baggy faded black jeans, completing the “effortless” K-pop aesthetic. Her look is a prime target for the “Sonminsu” trend. Fans are constantly seeking out these exact luxury pieces to capture that signature NewJeans “cool girl” energy.
“The airport is no longer just a place of transit; it’s a strategic runway where the ‘slouchy’ silhouette communicates both high-fashion status and a relatable, off-duty human element.”
Trending Now: The “Get the Look” Digital Culture

We now have AI styling tools and “Get the Look” accounts that can identify a beige Fendi jacket or a scarlet sweater within minutes of an idol stepping out of their van. This rapid cycle of “see-and-buy” has turned Incheon airport style 2026 into a major engine for the global fashion economy.

The Future of the Slouchy Silhouette
As we look toward the end of 2026, the oversized “shield” isn’t going anywhere. It’s more than just a passing trend; it’s a necessary evolution. For a globally-mobile idol, the baggy look offers a rare moment of comfort in a very public life. Industry experts think the next phase will involve even more technical fabrics and “upcycled” materials. We’re likely to see a blend of fringe and warm tones mixed into these massive silhouettes. Whether it’s for privacy, comfort, or a luxury deal, the slouchy silhouette is the definitive look of this K-pop generation.
