She posed for the 2025 issue in Bermuda with photographer Ben Watts and continues to shine with her positive energy and dedication to making wellness approachable through her Katie Austin App. The Virginia native, who now lives in Los Angeles, has traveled everywhere from Portugal to Montenegro to the Dominican Republic with the brand.

SI Swimsuit’s presence at Swim Week 2025 was nothing short of spectacular. Held at the W South Beach, the event featured a full weekend of immersive programming—from beachfront brunches and a poolside Apres Swimsuit celebration to a Coppertone-sponsored Beach Club and a dazzling Saturday night runway show. It was a high-energy mix of confident walks, flawless fashion and fierce girlboss vibes.

Her 2025 runway looks consisted of a stunning, trendy red and white polka dot top ($59) and bottom($59) from Toxic Sadie Swimwear, a western-inspired plaid look from Ola Vida and a snakeskin string bikini from Two Fish Swim.
