Joan Swimwear One Piece

This bathing suit was exactly what I was looking for. I ordered my usual size, medium in bathing suits (per size chart too). This bathing suit has minimal compression but the rushing on sides & as a result having some extra fabric in front are flattering. However, strangely the top was so big, despite me being larger on top & very long that in order to even remotely “adjust” it, I had to pull it to the very neckline & even that didn’t do it. Definitely not cut proportional. But, since I do love the design of the bathing suit, I decided to give it another try by ordering a Small. I did have some room in the belly area so I thought if I order a small, it’ll be tighter which is fine (hopefully not too tight) but perhaps the top would be cut smaller, shorter & more proportional? My concern is the difference in cut & if it’s significant? Questionable but still gave it a try.
