I really needed 3x, because I was warned ahead of time about the fit. I had to order 2x because of the limited quantities in white. It is fortunate that I fit the jumpsuit because I need it for a performance. But the structured fit for the upper body could be done better. I have to wear a sports bra to minimize size as well as its tight on the shoulders and collar. And the ease of the zipper, there's none. I like jumpsuits I can zip and unzip myself.
