Stunning Sports Illustrated swimsuit model Ally Mason turned heads in New York City in a showstopping cowgirl outfit.
To flaunt her flawless bikini body, she wore a belted black leotard and thigh-high leather boots. A little cowboy hat and whip finished the look.
“Saddle up,” she captioned the Saturday, November 1 share to Instagram. The carousel post included four pictures of her in the sexy Halloween costume, including one that revealed a cheeky rear view.
The comments immediately filled up with fire emojis and fans writing “yee haw.”
“Yee… but most importantly… hawwwwwwwww 🔥🔥🔥,” read one variation.
“You look soooo good 😍,” added another commenter.
“Looking this good feels like it should be illegal 🥵,” agreed a third.
Kiki de Montparnasse, a lingerie brand Mason often models for, wrote, “And she does it again🔥😍.”

Mason was a 2025 Swim Search Finalist for the Sports Illustrated swim brand that in recent years has spun out to include much more than the iconic print magazine. She also hit the runway for the SI fashion show this past May 31. The VIP-only, sold-out show featured mostly models from this year’s issue and took place at the ultra-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.
