Over the weekend of April 4-5, high school girls descended on the Oregon Convention Center to find their perfect prom gowns at Abby’s Closet. Now in its fifth year, the charity event collects donated prom gowns, bridesmaids dresses, and other fancy frocks to be given away free to young women who may have difficulty affording their own.

This year about 1,600 girls found dresses among the more than 4,500 that were donated (leftovers will be packed away for next year’s event). Abby’s Closet is open to any young woman with a valid high school I.D.
