Flawless ‘SI’ Swim model hits beach in flirty, peek-a-boo string bikini look

Flawless bikini model Ellie Thumann hit the beach in a flirty new look.

The Sports Illustrated swimsuit model took to TikTok to share photos of her revealing beach outfit — and others — in a Wednesday, July 30 photo share.

“I love summer,” she wrote over the pic, which was taken on a pristine white beach. She held a cowboy hat on with her left hand, and leaned on her right, showing off a frilly string bikini and tiny peek-a-boo cover-up. Her hair was wet, seemingly after a dip in the ocean.

Later pics showed various other tiny outfits that were more costume-y. On those she wrote, “But nothing compares to ellieween.”

“Your holiday,” wrote one commenter.

“Yearning for Halloween,” added another, who clearly shares Thumann’s love of the fall holiday.

Others asked for details of her looks.

The current Sports Illustrated swim issue marks Thumann’s third consecutive appearance in the iconic magazine. 

In May, she hit the runway for the Sports Illustrated Runway Show to close out Miami Swim Week. Also walking in the show were 2025 cover stars Livvy Dunne, Jordan Chiles and Lauren Chan (missing only Salma Hayek), plus models Xandra Pohl, Penny Lane, Ilona Maher, Katie Austin, Nicole Williams English, Ali Truwit, Camille Kostek, Achieng Agutu, Jasmine Sanders and Denise Bidot.
