Ellie Thumann just gave us a masterclass in monochrome dressing—and we’re taking notes. The three-time SI Swimsuit model and content creator, who’s been a longtime ambassador for Alo Yoga, showed off her latest all-green look that’s equal parts sporty, sleek and summer-ready. Naturally, her sculpted abs took center stage as she struck a few power poses in the middle of the day.

“🍵,” she kept her Instagram caption simple. View the post here.

The 23-year-old styled the set in a classy layered way, pairing Alo’s Airlift Suit Up Bra ($78)—a high-compression, second-skin sports bra designed with chic white stripes and an ultra-smooth, double-knit fabric—with the Accolade Short ($68), made from soft, midweight French terry. Thumann sized up in the shorts and flipped the waistband once for a casual, relaxed vibe. Draped around her shoulders was the matching Accolade Crew Neck Pullover ($128), a fan-favorite piece known for its boxy fit, ribbed trims and effortless look.

The look, all in Alo’s fresh “Spruce Green” shade, was styled to perfection with black sunglasses and a structured black handbag for an elevated finish. Whether she’s heading to a Pilates class, a press event or just strolling through Charleston, SC, where she lives with her older sister, Erin, Thumann continues to prove that activewear can double as a fashion statement.
