Bathing Suit NWT

Purchased a bathing suit online from SHEIN and didn’t like it. It’s new with tags (in respect to the fact that it didn’t come with tags but with the sanitary sticker on the bathing suit). Bathing suits on SHEIN are non refundable/exchangeable. Does not run true to size so I have included the sizing chart. I normally wear an XL and purchased the 3XL so please do measurements.
