I bought this product to firmly "contain & smooth" all my parts under a form-fitting formal gown. It served the purpose well, and I give it a high recommendation! It did NOT mash everything flat. There is a gather between the breasts which prevents uni-boob. The buttock and hips are also woven differently, so you dont have a flat butt. I am 5'7" and this came down to my knees. I guess it could be hiked up if you wear a short dress, but depending on how much, it could compromise the smooth factor. My event was during a blizzard, so I welcomed the extra layer and warmth, but I believe it would be pretty hot to wear in summer months.It fits as expected. I have seen other shapers perform better and it is losing some stretch after several wears but that can be expected with any product. I would buy this over again over most other popular brands but it's an honest product with an honest description.I wish it were a little longer, however this shaper felt good, and stayed in place. I need it for a very long gown and it holds me in in all the right places. I did add my own bra, after reading another review. It all works well together!I really like it except it provides no bust support. I ended up having to wear a strapless bra underneath it just so my dress fit properly. It is very comfortable to wear though. Just wish it had better support up top.Shaper was small on me and the bra offered no support. The fabric does not move with many outer layers, such as cotton.VERY TIGHTMay order another in black when the price comes down again.I wear a size 1x and purchased a 3x so it wasn't too tight. It was too tight anyway.
