I needed white swim bottoms but the fabric on these is far too thin and the panty inside is a joke - very little coverage and tissue thin with no fit to it. Definitely no tummy control. If you have any cellulite on your backside you can see the texture right through these, and thats when they're dry!  When wet Im certain these would be transparent. The legs fit great - slightly loose, which I wanted - but the inseam is too short for me so the waist fit at my hips, which showed the muffin top I want to conceal. If you need a dark color and don't need these to fit at the waist, they might work for you. I returned them immediately.
