Hi ladies, I am looking for a good brand of shapewear (as in camisoles/tank tops only) for layering or on it's own. It needs to be a slick fabric so that it will not cling to sweaters, etc. Also, it needs to be long enough to hit at the hips. I don't want to spend too much either... I have tried the new york & company bodyshapers, but even the xs is too loose for me (my waist is 25" and I have some pooch from having a baby that I need some help with). Any help would be appreciated. Thanks!
