Hailey Baldwin, 25, is back with another bikini photo! The model shared a photo dump from a recent vacation to her Instagram account on Saturday, Dec. 10, including one in a burgundy swimsuit. She added a sheer patterned cover up in the same color family over top the tiny two piece as she posed on a sandy beach, adding a throwback vibe with a red-and-white checkered bucket hat. No caption was necessary except a simple palm tree emoji!
