One piece swimsuit

Hello! I recently purchased this item from SeaFancy and was impressed by the quality. I haven’t worn it, this is brand new, the size M is too large for me. Instead of returning it, SeaFancy offered me a very small discount to keep it, so I’m looking to sell it here. I also have the receipt available if you'd like to see it. Feel free to make me an offer! https://www.seafancy.com/category/polka-dots-one-pieces/product/black-polka-dot-adjustable-straps-twist-front-ruching-tummy-control-casual-one-piece-swimsuit
