bathing suit anxiety

Just this morning I tried on a one-piece bathing suit and to be honest I wasn't that happy with the way my body looked in it. It was a little snug around my stomach area, but none too serious. So I put that one back and I tried on a size bigger, and so happens that one fit perfectly. Now I know all bathing suits run different but this one in particular, I actually had to go to 2x 😕. Not going to lie I'm a little bit upset and a little disappointed that im wearing 2x now. I have never worn that size before. But now I'm a little self-conscious about wearing it to the pool/beach now just because of what size it is. #P.S I actually bought the bathing suit because its cute lol
