This is a 3-piece swimsuit set: top and bottom, plus a skirt. The size is indicated as "9M" in the 5th photo. According to my research, this means it fits C/D cup bust sizes and a size M for the bottom, equivalent to clothing size M. It has only been worn once with an undergarment and is in excellent condition. It's a beautiful item and should still be usable, but please refrain from purchasing if you are overly concerned about used items. *It will be folded and slightly compressed for shipping with simple packaging. *Please be aware that there may be some folding wrinkles. Immediate purchase is welcome.
