Allison “Aly” Mason is back in the U.S. from her summer on the French Riviera, and she wasted no time in hitting NYC in a high-fashion look.

Wearing a low-cut, strapless leather dress and boots, the Arizona native and USC grad, 25, owned the streets of the Big Apple.

“Season opener 🍂🖤,” she captioned the Saturday, September 6 Instagram share. The carousel post featured four pictures of her in the same look. One later photo revealed that the dress had a slit up one side, and she was bare-legged.

The comments section immediately filled up with fire and heart-eyes emojis, including from fellow Sports Illustrated Swim Search finalist Dominique Ruotolo. Added Leticia “Tish” Martinez, also in the 2025 Swim Search class, “Slayyyyy🔥.”

“Love the dress,” gushed one fan. Another agreed, “Queen in black.”

“Whoa, season opener, vibes hit hard,” said another commenter. “Love this energy, can’t wait for what’s next, already hyped!”
