Stunning Sports Illustrated swimsuit model Allison “Ally” Mason took to Instagram to share her latest splashy fashion campaign, sizzling in the pool in one sexy look after another
The professional model and USC grad posted the sexy video for edgy lingerie and swimwear brand Kiki De Montparnasse on Friday August 8. In the share, she showed off her chiseled abs and flawless physique in a series of sexy bikinis — starting with a stunning turquoise one that popped against her bronzed skin — and lacy lingerie.
She also modeled a sheer red lingerie piece that laced up the front, an asymmetrical black bikini, a red two-piece with sheer paneling, and a sleek black one-piece. She’s in the pool throughout the video, meaning that even lingerie that wasn’t meant to be wet was soaked.
Mason, 25, wore the same butterfly necklace with every look.
The professional model was most recently a Swim Search finalist to be in the next print issue of Sports Illustrated swim. She already hit the runway for the iconic magazine’s fashion show to close out Miami Swim Week this past May 31. The sold-out show featured mostly models from the 2025 issue and took place on the pool deck of the glam W South Beach.
Also walking in the show were 2025 cover stars Livvy Dunne, Jordan Chiles and Lauren Chan, plus models such as Penny Lane, Xandra Pohl, Jena Sims, Ilona Maher, Katie Austin, Nicole Williams English, Ali Truwit, Camille Kostek, Achieng Agutu, Jasmine Sanders and Denise Bidot.
