Simone Biles Celebrates Her Birthday in a Backless Halter Dress on the Beach

Simone Biles celebrated her 25th birthday on Monday, and the dress code was decidedly Biles-has-mastered-the-beach casual. During a romantic getaway with her fiancé, Jonathan Owens, in Turks and Caicos, Biles showed off her look on Instagram: a backless halter dress in a pastel pattern and a pair of translucent sunglasses. "FINE 🥵💍," Owens commented on Biles's post before sharing photos of Biles on his own account.

From the front, the bodycon dress hits just above Biles's mid thigh before wrapping around to reveal the backless design and necktie details. The Olympic gold medalist completed the look with cat-eye sunglasses, a white pedicure, and braids that stretched well past her waist. Of course, our favorite accessory was Biles's massive diamond engagement ring, which sparkled as the couple soaked up the sun in honor of her special day.

After cuddling under a beach umbrella and sharing breakfast in the sunshine, Biles and Owens went for a stroll along the beach. Owens even wore a striped blue button-up and a matching hat that perfectly complemented Biles's ensemble.
