‘SI’ Swim model flaunts flawless physique in bra top, sheer skirt at ESPYs

She doesn’t often hit the red carpet, but when she does, Katie Austin does so with a bang.

The stunning Sports Illustrated swimsuit model and fitness guru, 31, wore one of the most daring looks of the night at the 2025 ESPY Awards, showing off her chiseled abs and flawless bikini body in a jeweled bra top and see-through, low-hanging skirt.

The sheer skirt required nude-colored bloomers underneath and created quite the optical illusion. The glittery outfit shone on the red carpet, and she California girl wore her expertly-highlighted hair down. The overall look was stunning.

The 2025 Sports Illustrated swimsuit issue marked the fitness influencer’s fourth time in the iconic publication.

The SI Swimsuit brand had the model work the red carpet at the ESPYs to ask celebrities to pick their favorite red carpet pose. Her outgoing personality shone as she got many sports celebs to goof around with her. At one point, she added a blue blazer to cover up her skin-baring look, but it didn’t last long in the searing L.A. heat.

The awards show was hosted by comedian Shane Gillis at the Dolby Theatre and aired on both ABC and ESPN+. Other celeb athletes in attendance included Olympic gymnast Simone Biles, alpine skiing comeback queen Lindsey Vonn, WNBA star A’ja Wilson, Buffalo Bills quarterback Josh Allen, and Los Angeles Dodgers superstar Shohei Ohtani.
