My local Target stopped carrying this brand (and plus sizes), so I was thrilled to find them on Amazon.  These are the most comfortable undies I've worn.  They don't ride up into a thong when you move.  They don't pinch around the top of your thigh.  They stay put!  And because they're made for plus sizes, the panty section is shaped properly so that's comfortable too.  The all-cotton construction is cool and easy to clean.  (They do not shrink after washing, either.)
