Swim Week is the ultimate celebration of summer style, and SI Swimsuit brought the heat once again. The two-day activation included a beachfront brunch, poolside programming, a Coppertone-sponsored Beach Club and an unforgettable runway show at the W South Beach on May 31. Each event spotlighted the brand’s ongoing commitment to confidence, inclusivity and redefining what it means to feel beautiful in your own skin.

Thumann’s 2025 runway looks included an edgy black studded string set from PARAMIDONNA, paired with a blue denim bolero from Denimcratic and a black cowboy hat from Zandria. She also rocked a cute yellow suit with green polka dots from Two Fish Swim.
