“I really liked my pink latex [swimsuit]. It was very Barbie,” the fitness influencer said. “It really reminded me of my mom’s [Denise Austin] old workout leotards and so that was kind of like a cool full-circle moment. My mom saw it, of course, and it also reminded her of what she used to wear on TV.”
Austin wore the Sanaz Latex Tank One-Piece Swimsuit ($134).

“We started [the collaboration] almost a year ago, probably right before last year’s issue came out. It’s just such a long process, and there’s so much time and effort and love that goes into it,” Harper said about wearing a piece from her line with B Swim. “So then to get the opportunity to wear it in the magazine is just like so insane. It was just a such a cool full-circle [moment]. I’ve worn a million bikinis in my life, but I’ve never worn my own.”
Harper wore the Saint Tropez Top ($96) and Venice Bottoms ($88) in the “Dune” print.

“All the bikinis this year were inspired by Wednesday Addams, which I think was really cool because Jenna Ortega just played that role in the Netflix series,” Dunne said. “I would say my favorite is probably the Gucci suit because I just feel like that was an iconic piece and I love the way it fit and it made me feel really confident.”
The LSU gymnast wore the GUCCI One-Shoulder Cut-Out Swimsuit ($720).
