What impressed us besides the fit and design of the Push-up String Bikini from Voda was the enthusiastic responses we received from our customers who were gracious enough to help us test these! The Push-up String Bikini features Voda's patent pending foam cups that are super lightweight and super effective. In addition, the padding appears very natural and none of the tops have underwire. Top ties at back and neck. All hardware are 14k gold plated and salt water resistant. Cups fit AAA, AA and A. Body: nylon/spandex, lining: polyester/spandex.
