Camille Kostek is giving fans another glimpse behind-the-scenes posing for SI Swimsuit. The 2019 SI Swimsuit Issue cover star, who recently celebrated her 31st birthday, shared a stunning throwback polaroid on Instagram.

She wore a red-and-white striped bikini with a triangle-shaped top and side-tie bottoms and showed off her toned stomach. Kostek held the ends of her long blonde locks that were styled into two symmetrical  braids with her curtain bangs perfectly blown out to frame her face. She donned two dainty gold necklaces.

“fittings for my favorite shoot of the year☺️,” she captioned the post she shared with her one million IG followers. “Sports Illustrated Swimsuit 2023 loading …. 📷🌈🌞.”

She tagged MJ Day, SI Swimsuit editor in chief, and Margot Zamet, the brand’s fashion editor, in the pic.

“Wow😍,” fellow 2023 SI Swimsuit model Brooks Nader wrote.

“TOO HOT TO HANDLE,” gushed 2023 SI Swimsuit rookie Mady Dewey.

Kostek just wrapped up her photo shoot for this spring’s magazine in the Dominican Republic. She made her SI Swimsuit debut through the Swim Search in 2018 and has been featured in the magazine every year since. Kostek landed the cover as a rookie in 2019 and has been a calendar cover star three years in a row. 

“When asked what I do, I typically lead with ‘I’m a model for Sports Illustrated Swimsuit’ because I am SO proud to have achieved such an honor to be able to say I’m a part of the @si_swimsuit legacy,” Kostek wrote in an IG post last year. “I used to hesitate leading with that title because of the judgement that follows by those who don’t understand the meaning for a lot of us women that have dreamt of one day being able to say this. As our editor in chief @mj_day shared with us today: ‘We know we are more than a ‘Swimsuit Magazine’ and you are far more than a ‘Swimsuit Model.’ You are entrepreneurs, wellness enthusiasts, thought leaders, role models and changemakers. Your ambitions shatter ceilings and empower women all year long. We invite you to join our mission.’”

When the former Patriots cheerleader found out that she would be featured on the magazine’s cover in ’19, the sweet moment was captured on video.
