I picked up a pack of these because I love the string sides. After wearing the first one, I remembered why I prefer t-backs. These rode up on me and produced visible panti-lines on my jeans. Uggghhh! I threw them away.
I like the style of these. But, they are rather poor quality. The started falling apart after a few washings, and I wash my clothes carefully. I'm not a fan of the colors, either. Also, they're kinda baggy, but maybe I just need a smaller size. Overall, I wouldn't recommend them unless you want cheap underwear to throw out.
