Once on, this tank felt snug and comfortable. Nice support. Reminded me a bit of wearing a bathing suit. I really would have liked it if it hadn't been so horrible trying to get it on and off over the head and shoulders.  There is no stretch or give in that arena. I simply am not going to struggle and do a contortionist act each time I try to wear it. It wasn't just me. My daughter tried it also and had the same problem. I had ordered a medium. My daughter said maybe, just maybe one of the Olsen twins might be able to wear it.
