I was looking for no show underwear at an affordable price point and found it. I've included pictures comparing Anzermix to Victoria's Secret for sizing help. I ordered an XL and they are comparable to the VS Large. They are not seamless. There are seams on both sides and the back, but they are no show for the most part. I do occasionally have issues with them rolling, but I believe that's the nature of laser cut clothing and it's not bad enough to make wearing them a problem. I would absolutely buy these again. They are comfortable and cute and mostly no show. The colors are true to what is advertised. I do wish they came in a pack of neutral colors, but bright pink works for some people. Overall, I'm happy with these and wouldn't hesitate to buy them again.
