Guilty, Dresslover! I recently realized I hadn't updated my undies *since my daughter was born.* My bras, yes. My old faithfuls, no. (I blame Tide with Bleach - they really did look and feel OK!) Needless to say there has been a major Under Overhaul since. Also, working out helped since they no longer fit - woo!
Funny side story: My husband, upon seeing Old Faithfuls in the trash, was like, "Why are you throwing these out?" Um... darling, I hate to break it to you, but your underwear gets thrown out too. You just don't notice because the Tighty Whitey Fairy mysteriously always comes and replaces them!
