Brand new, unused item with tags! I purchased this from SEA DRESS but am selling it because I no longer have the opportunity to use it(^^) It's a size M. Please refer to the 6th photo for length and other details. The following is quoted from the official website: - A romper swimsuit with a relaxed feel thanks to its open back design. - Made with UPF50+ material that is highly stretchy and quick-drying. - An excellent item that allows you to adjust the chest height freely and the fit with the back ribbon. - Features tucks to cover the hip area and a wide hem design to make your legs look slimmer. - Comes with convenient side pockets. - Built-in bra shorts are included, so you can enjoy the beach with just this one piece.
