Miami Swim Week has kicked off for 2025, revealing a “really risque” bikini trend that is all over the catwalk, and the return of a bikini trend we thought we’d seen the last of. Picture: Getty

Models walking for various different brands have been spotted in an array of revealing designs – such as this lemon one-piece from Salty Mermaid that features a star across one boob. Picture: Getty

Designer Ema Savahl has also embraced the trend, creating this cossie that resembles lingerie with its flesh-flashing features. Picture: Getty

The swimmers leave little to the imagination. Picture: Getty

This unique bikini from Clarisse Céleste turned heads at the annual swimwear event, sponsored by Paraiso and By Art Hearts Fashion. Picture: Getty

The statement top appeared to look like coral but was actually made from rope. Picture: Getty

US brand Autty Simone also got in on the nearly-naked trend with this wild black cossie. Picture: Getty

It fully flaunted the model’s bottom. Picture: Getty

Metallic numbers, such as this one from Strange Bikinis, also dominated at the week-long showcase in Florida. Picture: Getty

Some designs were more dainty – but always revealing, such as this gold two-piece from Leslie Amon Resort. Picture: Getty

Salty Mermaid’s runway show also featured a swimming costume that offered no coverage on the bust, with the model instead opting for sea shell nipple pasties. Picture: Getty

The fishing-net style swimmers were made from a hot pink fabric. Picture: Getty

Some bikini tops were more like nipple tassels than bras, such as this neon green number from Delarose Sisters. Picture: Getty

“his year’s biggest trends leaned into the naked trend that’s had a hold on fashion lately,” one commentator wrote for online fashion publication L’Officiel USA. Picture: Getty

“Many Miami Swim Week bikinis pushed the envelope, edging towards nudity.” Picture: Getty

And just when you thought you’d seen the back of the “underboob”, it makes an unexpected 2025 return. Picture: Getty

The bust-baring design was popular about 5 years ago but had dropped off in recent years. Picture: Getty

Recent pictures from Miami Swim Week show it is on the rise again. Picture: Getty

“Almost every girl is popping out from under her bikini,” one social media user noted. Picture: Getty

One brand, Belle D'Amour, decided to show off what it looks like to wear two cossies at once. Picture: Getty

While the Sugarpuss show leaned in to cowboy core. Picture: Getty

One model in the Giannina Azar show flaunted her matching clutch bag which paired to her blue beaded bikini perfectly. Picture: Getty

I don’t think Baywatch bikinis are ever out of fashion. Picture: Getty

“Sexy swimwear doesn’t have to show everything.” Picture: Getty

Full coverage bikinis are also said to be in trend for 2025. Picture: Getty

Megan Thee Stallion also took to the runway to launch her own brand, Hot Girl Summer Swimwear By Megan Thee Stallion. Picture: Getty
