Over 30,000 votes were cast for the awards, which are sponsored by online retailers HerRoom.com and HisRoom.com, and a few of the winners might surprise you.

First off, a high-waisted granny panty won for best women's underwear (perhaps Rihanna's recent getups are to blame?), the overall favorite bra went to a racer-back style for the first time in the four-year-old contest, and the best shapewear didn't go to Spanx.
