NVUD Black Underwire Tie Front Bikini Top. This top features adjustable spaghetti shoulder straps, gathered cup details, a structured underwire support design, and an adjustable front-tie accent. Super flattering and sleek, it can easily match with any black or patterned bikini bottoms! I love that it ties in the back because you can adjust it to fit you perfectly. Gives me complete cottage core / coquette / retro / romantic vibes .Material: 78% Nylon, 22% Spandex Size: XL.
