Who knows whether Harry Styles wears boxers, briefs or thongs, but want we do know is that he wore a CANDY THONG!!

At the One Direction concert a fan tossed a candy thong on stage and Harry decided to put it on!  Things got a little naughty when other band member, Zayn Malik bit a piece of it off.

Well well well boys, One Directioners loved this!  Who knows maybe next time fans will toss more naughtier objects onto stage since the boys seem so down to do anything for their fans!
