Query: the best!

This is the most comfortable brief you'll ever wear. Unless you like the feel of shifting, tugging and binding, these are the panties you want. They stay in place and stretch all ways for a perfect fit, no matter what your particular shape. Love 'em! Wish Sears would have kept the line going, but I'll buy them from anywhere I can get them.
