Tucks in all tummy fat while making your butt pop out. It does the job like it should. Downside is that the material is very thick and heavier than most shapers and it's very noticeable if someone was to hug/feel you. Especially the zipper in the front. Yon can totally feel them through your clothes. Also, it is very tight of course so don't wear it for really long periods of time. This is actually the best shaper I own but sadly not as comfortable as the other ones so I only wore it once on a trip. Still would recommend this!
