At first I, open my, package and thought it might be too small but when I put it on it fit well,  tight,  but not overly tight,  it's comfortable as far as shapewear goes and it does smooth my midsection out.  I love that it's a thong.  No panty lines or flattening of my barely there booty lol. I also love the material,  it's thickish. I wished it was maybe an inch longer,  and  I have a short torso,  if your long torso, or want more coverage,  they sell another one that's a little longer and you should buy that one. I am thinking of buying it because I really like the build of this.  It also has bones in front and back so it does not roll at all! You can't beat the quality for 10$!
