Billlie's Tsuki Stuns at Prada Japan and Fans Can't Handle It

When Billlie's Tsuki stepped out at Incheon International Airport on March 26 to fly to Japan for a Prada event, she probably didn't expect to break the internet. But that's exactly what happened. Photos from her airport departure, featuring a sleek slicked-back high ponytail and a sharp, polished look, spread rapidly across fan communities — and once people got a clear view of her proportions, the reactions started rolling in fast.

The revelation that caught fans most off guard? Tsuki is 170 centimeters tall. For a member of Billlie who projects an often-sweet, compact presence on stage, that height caught a lot of followers by surprise.

The Moment That Went Viral

The airport photos themselves tell the story. Tsuki's slicked-back ponytail pulled her features into sharp focus, and her overall silhouette — long-limbed, lean, and with the kind of proportions that look almost architectural in photographs — had fans reaching for superlatives. "She's lean like a cat and so gorgeous," wrote one commenter. Another called her "a tall rabbit" — a nod to her group's bunny-themed branding — while others simply wrote things like "Her proportions are unreal!"

Korean netizens were equally stunned, with comments like "Wow, didn't know she was that tall?" surfacing across multiple platforms. For many, it was a moment of genuine surprise: Tsuki has always had a strong visual presence, but seeing her full-length figure displayed so clearly in press shots made something click for fans who hadn't done the math before.

The Prada event in Japan was the destination, and attending it placed Tsuki squarely in the company of global luxury fashion brands — a notable step for an idol whose profile in the fashion world has been steadily rising.

Tsuki's Fashion Journey: Building a Name in Style

This moment didn't come out of nowhere. Tsuki has been developing a genuine fashion identity over the past year, and her appearances in brand contexts have become increasingly prominent.

Earlier in 2026, she attended the 2026 F/W Seoul Fashion Week alongside fellow Billlie members, cementing her place in the front rows of Korea's premier fashion events. That same period saw her active presence at multiple showcase events, where her styling choices consistently drew attention.

More significantly, in March 2026, Tsuki was appointed as an ambassador for &PAIR by ViCREA, a Japanese haircare brand — with her campaign launching on March 26, the same day as her airport departure for Japan. The timing underscores how her fashion and beauty commitments now operate on an international scale.

Before this, she and fellow Billlie members Haruna and Moon Soo-ah were named exclusive models for DHOLIC, the popular Korean fashion brand. Each of these appointments reflects not just a celebrity endorsement but a recognition of Tsuki's specific aesthetic — one that balances the approachable charm expected of an idol with a sharper, more editorial edge.

Who Is Tsuki? The Story Behind the Face

For those less familiar with Billlie's lineup, Tsuki's background is worth knowing — because it adds context to why she carries herself with such ease in fashion settings.

Born Fukutomi Tsuki on September 21, 2002, in Osaka, Japan, she is one of two Japanese members in Billlie, the six-member group under Mystic Story Entertainment. Before her current career, her path through the K-pop industry was anything but straightforward. She was previously a trainee at SM Entertainment, participated in JYP Entertainment auditions, and was a member of the Japanese group MAGICOUR. Each of these experiences contributed to a performer who debuted with an already formidable set of skills.

In Billlie, Tsuki serves as the group's main dancer and sub-vocalist — roles that explain the physical precision and body awareness visible in every photo she takes. Her ENFP personality (according to MBTI assessments she's shared) adds a warmth to her charismatic exterior, and her fandom nickname — Tarutaru, from the group's bunny-themed fandom name — captures the duality fans love: serious performer, irresistible charm.

Her role models include BoA and Girls' Generation, which gives some insight into her vision for her career — artists who built international profiles not just on talent but on longevity, versatility, and a clear personal brand.

A Year of Big Moments

The Prada appearance is part of a stretch of months that has seen Tsuki's profile rise noticeably. In February 2026, she completed a full marathon on the MBC variety show "Extreme 84" — an achievement made more remarkable by the fact that she was reportedly dealing with a physical injury at the time. The combination of toughness and determination resonated strongly with fans watching the show.

Also in February, a set of Instagram photos she posted — featuring a mature, editorial styling direction that felt different from her typical on-stage image — generated significant buzz, with nearly 6,000 comments and an overwhelmingly positive response. Fans described the post as a confident artistic statement, and it circulated widely among K-pop communities discussing visual identity and idol image evolution.

She's also currently filming the drama "Kkkomu," in which she plays an empathetic fairy — a role that feels fitting for someone who has built her public image on emotional expressiveness and genuine fan connection.

The K-Pop Idol in Luxury Fashion: A Growing Presence

Tsuki's Prada appearance is part of a broader trend worth noting. K-pop idols have become an increasingly central fixture at luxury fashion events globally, with brands recognizing the enormous reach and engagement that K-pop fanbases bring. Invitations to events like Prada's Japan activations are no longer surprise appearances — they are deliberate partnerships built on mutual recognition of cultural influence.

For Tsuki specifically, the moment resonates because it isn't just about the event. It's about a narrative that's been building: a Japanese idol trained in Korea, performing in a Korean group, now attending luxury European fashion events in Japan, and being recognized for her own aesthetic identity across all three contexts. That kind of cross-cultural positioning doesn't happen by accident.

Whether fans knew she was 170cm or not, they knew she looked the part. The viral reaction to her airport photos is, in that sense, just the internet catching up to what the fashion world has apparently already figured out: Tsuki has the kind of presence that commands attention in any room.
