One size should have been a caveat, but no, I bought this anyway.  It's very stretchy, feels like it's made of thick opaque panty hose.  Problem is, it feels like you're being choked by a midget while you're wearing it, as even the neck is small.  The sleeves are not long enough and shrink back up your arms, and the worst part of the fit is the hips-to-waist area.  The material rolls up your stomach as you move until your belly button is showing, forcing you to constantly pull it down.

I bought this for a costume; I'll wear it for parade day, but it will be going to the donation stack as soon as I'm done with it.
