Hillary Steen, a senior at Clarkstown South High School, works on a display of donated formal dresses during a Prom Dress Drive at the school in West Nyack May 1, 2010. The event was being held in cooperation with Project Prom, a non-profit organization that collects and distributes dresses to girls in the community and New York City, who would otherwise be unable to afford their own. Over 100 gently used formal dresses have been drop off and Project Prom will be accepting donations until May 7th. Donations can be dropped off at the school office during school hours. The school is located at 31 Demarest Mill Road in West Nyack.
