This charity event is a local favorite, with hundreds of St. Louisans taking to the streets to participate in a "brief" run in their unmentionables before partying their inhibitions away at Ballpark Village.
Speed and style are both desired traits here, as the organizers arranged costume contests for best female costume, best male costume, best couple costume and best group costume.
It's all for a good cause, too. Cupid's Undie Run is organized in an effort to find a cure for neurofibromatosis (NF), a genetic tumor disorder that impacts 1 in every 3,000 births.
