I'm picky when it comes to undies. They have to be just the right material. They can't squeeze me in the wrong places. They shouldn't ride up on me throughout the day. They shouldn't require excessive rearranging when pulling your pants on after pooping. They also have to come in different colors and patterns. Oh and be under $25 a pair. If you're picky like me, try meundies. I love the ones I've bought so far.
