So I was nervous since I gained weight so I got a M/L just incase. I could have bought a S/M because the body suit is very stretchy which is great and opens from the bottom which is helpful. A strapless bra helped since I don’t really have boobs. The leg covers constantly fall while walking so use fashion tape and the gloves were a little big but I am a petite person. I am 4”11, 142 pounds, small top, thick bottom. It doesn’t come with a mask I had a hard time finding a matching mask and fan but overall I was still happy going to New York comic con. I did get a lot of compliments so thank you fashion nova🙂
