Bella Hadid is a fan.

Though summer doesn’t officially start until June, our celebrity bikini watch efforts are already in full swing. Notable recent sightings include Bella Hadid wearing the same crinkle bikini as J.Lo, racking up a casual combined nine million likes on social media and Lili Reinhart in an uber-bright neon bikini (also a look Jennifer Lopez has been behind). Other emerging trends among the celeb set this season include French-cut bottoms, animal print, and optic white. But none have been quite as attention-grabbing as the under-boob bikini. Or, as one of our colleagues calls it, neathage, which is apparently a clever mashup of “cleavage” and “underneath.” . Bella Hadid posted not one, not two, but three selfies in the trend, Rita Ora is on board, and if you’ve been watching Netflix’s “Too Hot to Handle” series, you’ll have noticed the revealing style is ubiquitous on the show, too. And while this look leaves us with a lot of questions—what happens when you swim in it? Are these micro bikini tops or just regular tops pushed up?—we’re predicting it’s a trend that will only gain steam. Scroll down to see how celebs and influencers are styling the under-boob bikini now.
