This year’s SI Swimsuit photo shoots featured some pretty iconic bikinis. Melissa Wood-Tepperberg wore real sea sponge. Sixtine posed in a massive dark green leaf suit. Katie Austin wore a Denise Austin-inspired one-piece. Madisin Rian mixed the summer‘s biggest trends—mesh and cut-outs—in one suit. Megan Fox stunned in beads of every single color. Christen Harper sported one of her own designs.

In honor of National Bikini Day, SI Swimsuit’s favorite holiday, we pulled together a gorgeous gallery of some of our favorite photos and looks from Dominica, Puerto Rico and the Dominican Republic this year. Below are 10 stunning swimsuits that serve as perfect summer swimsuit inspiration.

“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).

Christen Harper

“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).
