Women's Patagonia 2-piece bathing suit. Both top and bottom are size small, however the bottoms have always felt on the looser side to me. The top is adjustable depending on how tight you tie it.
This suit is used but have taken great care of it. No holes, tears, etc. Coloration is not as bright as it once was, but still has original liners in the top.
I have loved this suit but it's time for someone else to love it now!
