This item worked for me. I started with a medium they did not look right. It made my but look way too big it was unnatural. My boyfriend suggested I get a smaller size. So I bought a small. It worked great. Although i have only tried with jeans i love them. You can't even tell its fake. But I had to size down I wear a seven pants size and had to get a small. So if you are thinking of this product my advice would be to size down. You want it to be tight so it won't move around. That's the key to making these work. Sizing is everything. To big and you'll see lines.
