Flawless SI Swim model risks dress with a sheer, lacy front

Flawless SI Swim model Ally Mason hit the runway at New York’s fashion week, risking a breathtaking slip dress that featured a sheer, lacy front. The stunner — by the designer L’Agence — fell all the way to the floor, and a sparkly evening bag finished the look.

Jet-setting Mason, who was most recently in Doha for the ultra-glam Art Basel art fair and parties, wore her blonde hair down.

As always, her caption was brief. “L’AGENCE FW26 🖤✨ @lagencefashion @tararudesdann,” she wrote with her eight-image carousel, posted Thursday, February 12. Along with her photos of her working the party in her finished look, she included some fun behind-the-scenes-moments, too: Mason getting her hair and makeup done, and the model board.

“Oh my God! Stunning!!!😍,” wrote one commenter. She replied with two red hearts.

“Beautiful girl,” added another.

“Drop dead gorgeous wow,” agreed a third.

“No one prettier than you,” commented a fourth.

Fashion Week runs through the weekend, officially ending on Monday, February 16.

Mason walked in last year’s May 31 Sports Illustrated Runway Show that closed out Miami Swim Week and was a finalist for the brand’s prestigious Swim Search. The native Arizonan graduated with honors from the University of Southern California.

Also walking in the show were 2025 cover stars (and gymnastics phenoms) Livvy Dunne and Jordan Chiles, plus models such as Penny Lane, Denise Bidot, Xandra Pohl, golfer Brooks Koepka’s wife Jena Sims, Olympian Ilona Maher, fitness guru Katie Austin, NFL WAG Nicole Williams English, and Gronk’s girlfriend Camille Kostek.
