The Prom Dress Exchange was created more than a decade ago as a prom-dress drive serving just a few high-school students. But a few years ago, Laura Bauer became president of the organization and has since turned it into a full-fledged nonprofit that reaches hundreds of kids. Bauer and fellow volunteers spend the year collecting and storing gently used prom gowns and accessories, many of them donated, in preparation for a one-day blowout of affordable formalwear each March; they also collect jackets, slacks, belts and shoes for the boys. With just $10 and a student ID, prom-goers can score a full outfit for the big night, plus on-site tailoring. Sounds like a reason to dance!
