How K-pop Idols keep their bust supported: All the bras, brands, tips & styling hacks

With Singapore’s heat currently doing the absolute most, the struggle to keep our bras — and our girls — comfortable is very real. Between sweat-soaked bras, stick-on pads losing their grip through the day, and straps that feel like they’re piercing your skin, finding the perfect bra can feel like a full-time job.

With so much struggle in finding the perfect bra, it’s hard not to wonder how K-pop idols seem to look effortlessly supported through everything. From performing high-energy, intense choreography at sweltering outdoor festivals to getting soaked at the wet stages of Waterbomb, somehow everything seems to stay firmly in place.

And while they rarely spill the tea on exactly what’s keeping the girls safe and sound, we’ve been doing some digging. From supportive bras to clever boob hacks, here’s the ultimate guide to keeping your breasts pretty, perky and firmly in place, no matter how sweaty or chaotic your day gets.

For supportive bras made for fuller busts: Lefee

Known as the “Waterbomb Goddess”, Kwon Eun-bi has become a fan favourite for her stylish bikini tops and bralettes worn during her Waterbomb performances, all while somehow surviving intense floorwork and splashes of water without a single wardrobe malfunction.

Eun-bi recently spilt some backstage secrets on Twin Mirror Show, hosted by fellow K-pop female soloist Jeon Somi, where celebrities share some of their favourite beauty and styling hacks.

First up: the bra itself. Eun-bi recommends finding one with just the right amount of wire support. Too thick or rigid, she explains, can become seriously uncomfortable, especially when you’re expected to dance through an entire choreography.

She says she switches between both Korean and international brands, but one of her go-tos appears to be Korean lingerie brand Lefee. While the brand name was redacted during the show, fans have pointed to Lefee based on the first letter she revealed and its prominence in the South Korean market for accommodating bigger cup sizes.

For sweat-proof support for hot days: Boob tape

For outdoor performances, a hack that’s sure to come in handy during Singapore’s blazing heat, Eun-bi has another trick up her sleeve: boob tape.

She says kinesiology tape is her go-to for keeping everything secure, but her advice goes beyond simply finding one that sticks. For Eun-bi, the real test comes when it’s time to take it off. Finding a tape that offers strong support without being harsh on the skin is key. After all, there’s no point in finding a tape that keeps everything in place if it leaves your skin red and irritated afterwards.

If you’re curious to try it for yourself, the tape she uses and even gifted Somi is available here.

For extra cleavage: Silicone bras

Eun-bi’s take on silicone bras has also evolved. These days, she says she prefers styles that create a lifted, push-up effect rather than simply pushing everything together for extra cleavage — a preference Jeon Somi seemed more than happy to agree with.

For wireless support that still gives shape: Calvin Klein

Former idol and Crayon Pop member Way has also shared a glimpse into her idol-era bra rotation. She reveals that she used to wear Calvin Klein’s wireless bras, which she found offered a good balance of support and shape. The thicker, water-resistant fabric also made her feel more secure, especially when performing.

Beyond performance, Calvin Klein also proves that comfort doesn’t have to come at the expense of style. BLACKPINK’s Jennie, a longtime brand ambassador for Calvin Klein, has been spotted sporting its bras and clothing in countless looks both on and off stage. She has even fronted her own capsule collection with the brand, giving fans a glimpse into the everyday essentials that make up her wardrobe.

For stylish lace bras that k-pop fans love: Victoria’s Secret

TWICE’s 2025 Victoria’s Secret performance featured a series of PINK looks, including the lace bras that quickly became fan favourites.

The girl group sent the internet into a frenzy with their special performance at the 2025 Victoria’s Secret show, but it wasn’t just the performance that had everyone talking. Fans were equally obsessed with the lace bra designs, with the fit and detailing quickly becoming a major talking point — especially the now-famous “Tzuyu bra.”

The hype didn’t stop at the runway. Multiple creators took to TikTok to share their reviews after getting their hands on the bras, even as they became increasingly difficult to find. And despite the sold-out status, those who managed to snag one largely had good things to say about the fit and design.

But Victoria’s Secret isn’t just reserved for the runway or the stage;, its bras have also made their way into the everyday styling of K-pop idols.

aespa’s Ningning went viral late last year for strutting through the airport with her girls looking perfectly supported and seamlessly smooth beneath a form-fitting, long-sleeve black top. Despite her rushed movements within the airport chaos, there were barely any visible lines, leaving everyone intrigued by what bra she was wearing underneath.

Although never directly addressed by her, Ningning later gave fans a glimpse of her innerwear wardrobe in a spicy bikini mirror selfie on Instagram, where she poses in what has been speculated to be the Victoria’s Secret Lightly Lined Wireless Bra, which looks to be the closest match.

Designed with a smooth, seamless shape and soft material, the wireless style is made for everyday comfort while keeping things discreet under fitted clothes. In Singapore, it’s available in classic black, as well as white and praline. If visible bra lines are your personal enemy, this simple yet idol-approved piece might be worth adding to your rotation.

For movement and support: Venus

And of course, we can’t talk about fuller busts without mentioning the queen herself: TWICE’s Jihyo. The K-pop star is now the face of leading Korean lingerie brand VENUS, which offers everything from everyday essentials to sporty styles.

Known for her high-energy performances and vigorous choreography, having a bra that stays supportive and secure through all that movement is no small feat. VENUS gets her seal of approval for its comfort, support and ability to keep everything feeling firm and in place, even when she’s giving it her all on stage.

While Venus doesn’t offer direct shipping to Singapore just yet, you can score very similar pieces at Cotton On. It’s an easy way to get that comfortable and cute Korean aesthetic locally.

For versatile bras for every outfit: Verish

A rising name in the Korean lingerie scene, VERISH has already earned some serious star power, with BLACKPINK’s Jennie spotted wearing the brand on multiple occasions, from stage performances to workout looks. Stylish enough to make an appearance beyond the gym, yet supportive enough to keep up with her active schedule, VERISH makes a pretty convincing case for lingerie that can do both.
