So I bought this as something to wear under a dress to smooth out some lines and suck a few things in, and it works alright for that.  Doesn't really make me 2 sizes smaller, but it helps.  I laugh, however, when they advertise this as a shirt or dress.  The fabric changes thickness and texture around the breasts and butt.  No way I would ever use this as a dress or shirt, but it works fairly well as slip/girdle type thing.
