Organic High Neck One Piece Bathing Suit

This bathing suit is beautiful, flattering, and high quality. However, it does run a bit large. For reference, I am 5’0, about 140 pounds, 36B, and typically wear a size 6/8 jeans. I ordered my usual size, a 6/8, in this swimsuit, and it was a bit baggy and had extra fabric hanging loose on me. I have requested an exchange for a 2/4 and I am hoping it will fit me better :)
