Ladies...if you washed your bra everytime you had a little UNDERBOOB SWEAT, you'd spend your ENTIRE LIFE at the washing machine!  So...How often SHOULD you wash your "double-barreled-slingshot"?  According to one expert, the correct answer is...wash it after you wear it seven or eight times.  A survey a few years ago found the average woman owns about 15 bras, and DOES wash them after she's worn each one about seven times.  What I want to know...is that the SAME FOR PANTIES AS WELL???
