Ellie Thumann knows how to turn any setting into a style moment—and her latest look proves that even a cozy activewear set can be beach-day chic.

She flaunted her sculpted midriff in Alo’s Airmesh Venus Bralette ($48)—a breathable, micro-mesh piece designed for lightweight support and style. Over it, she tossed the new Cropped Accolade Crewneck ($118) around her shoulders for a layered, laid-back vibe. She completed the look with the Accolade Shorts ($68), with a rolled waistband and French terry fabric giving off an effortless, comfortable fit and charm.

“Year three, oh my gosh. I feel like it never gets less scary,” she said while on the red carpet at the official 2025 issue launch in New York City in May. “This part is very intimidating, but I feel like I’ve grown so much over the last three years. And the feeling of going down the elevator [from] the first year to now is so surreal. It’s been so nice to reunite with everyone as well, and I’m just excited for a really fun night.”
