Summer break will be over before we know it, and now’s the time to stock up on festival essentials, sunglasses and other staples for the skin-baring season. If you’re seeking for stylish alternatives to bikinis, look to Olympian Simone Biles, J. Lo, Blake Lively, Martha Stewart (who made history as the oldest Sports Illustrated Swimsuit cover model) and other beach-loving stars for inspiration.

Stewart posed for SI last year at 81 in pieces from Norma Kamali, Monday Swimwear and Isa Boulder, among others. Superstar athlete Biles — who just became the most decorated gymnast ever — regularly shares her vacation looks on Instagram, including one-pieces by Burberry, Mikoh, Fendi, Riot Swim and more. And Sydney Sweeney, Hailey Bieber and Kendall Jenner are among the stars who’ve worn Gooseberry’s deep-V swimsuit.
