These are a game changer! What a difference they make under your clothes. I wish I could afford several pair. They make you look smooth and sleek. I never realized what proper undergarments could actually do for you until now. Don't hesitate to buy these. Firm support yet they feel like you're not wearing anything at all. For reference, I wear an 18 in pants and a 1x in tops and I got these in a 1x and they fit perfectly. Just remember to CUT the tag off, don't pull it like I did.. I ended up having to sew up the small hole I made.
