What's better than really hot stars in gorgeous clothing? How about really hot stars in various stages of undress? And though our usual topic of conversation centers around fashion of a higher brow, we have absolutely no problem digging into the archives in honor of perhaps the most epic holiday known to man: National Underwear Day. Last we checked, there's really no appropriate card in the Hallmark aisle, so we decided to say "Have a great day" in photos and GIFs. Enjoy!
