Allison “Ally” Mason has done it again, dropping another flawless bikini series to her Instagram.

In the Thursday, August 21 share, the USC grad and Sports Illustrated swimsuit model published five stunning high-fashion pics in the same colorful print bikini — including string bikini bottoms and a tiny bandeau top. The bronzed model absolutely glowed in the pics, which were taken on a sun lounger in super-glam Saint-Tropez on the French Riviera. In the pics, she leaves her expertly highlighted blonde hair down and wears a natural makeup look. In some pics, she sips on a green drink.

“Summer lovin,” she captioned the carousel post of five images.

“What a babe,” wrote one commenter.

“Absolutely beautiful and cutest,” said another.

“So so pretty!!” agreed a third.

“Can she get any hotter?” raved a fourth.

Mason, 25, was a 2025 Swim Search Finalist for the iconic Sports Illustrated swim brand. She has already hit the runway for the magazine’s fashion show to close out Miami Swim Week this past May 31. The VIP-only, sold-out show featured mostly models from this year’s issue and took place at the glamorous W South Beach.
