Bwhahaha. I know what you mean. My jammie' pants don't want to cooperate. I have to tie them super tight at the drawstring. :/! but at least you know you're losing!
LOL my pants are ok, because they all have crazy stretchy elastic in them. But while I am walking, my pants stay where they should and my underwear fall down...so I am trying to inconspicuously hike them back up! LMAO
