The swimsuit runs a bit small. It's a 3-piece set: bikini top, bottoms, and skirt. I've only worn it once, about 4 years ago. It has underwire. The design allows for adding extra padding to the cups. Instant purchase is OK. Please check the condition of the item in the photos. Due to shipping costs, it will be folded compactly for packaging, so please be aware of that. ----------------------------------- Swimsuit / Bikini / Separates / Skirt / Body-covering / Yellow / Frills / Tankini / Underwire / With underwire
