Livvy Dunne's bikini collection is never going out of style. Dunne, 22, took to Instagram on Wednesday, July 30, to show off a swim moment in Long Beach Island, New Jersey. In the snap, she rocked a blue-and-white bikini featuring a triangle top. The design featured underwire cups with half of the top complete with a blue background and white spots. The other half was finished with an ivory base embellished with blue florals. The gymnast elevated her look with diamond stud earrings and a white baseball cap, which she wore backwards.
