Stars have no shortage of stylish swimsuits.

This year, Hollywood’s favorites, including Gisele Bundchen, Simone Biles, Bella Hadid, Kim Kardashian, Brittany Mahomes, Hailey Bieber and more have shown off their bikini style in super sexy looks.

Take Mahomes, who slayed in a bubblegum pink suit only one month after giving birth to her daughter Golden, whom she shares with Patrick Mahomes. The number featured thick straps, a square neckline and a textured silhouette. She paired the look with clear Saint Laurent sunnies and smiled softly at the camera.

Biles also looked effortlessly cool in a leopard-print bikini on February 20 while enjoying a trip to South Africa with her husband, Jonathan Owens. Her set featured a halter triangle top and cheeky bottoms, which she accessorized with layered necklaces and black shades.
