Yes, it's a little odd to dedicate an entire day to your underpinnings, but the day is here whether you like it or not, so why not treat yourself to some brand new undies from our Underwear Guide and jump on that bandwagon, thong in hand?
We're especially fond of the Hanky Panky Lace Thong ($18) for its thick waistband that doesn't pinch in the wrong places. Other top picks include Gap's Cotton Teeny Bikinis ($8.50) and colorful Boy Briefs from Victoria's Secret Pink.
