(CBS) — Girls traveled from across the Midwest to a South Side school to get everything they need for prom — for free.

The first girl in line outside of the Price School, 4531 S. Drexel Av., arrived at 9:30 p.m. Friday. At 7 a.m. Saturday, an hour before the doors opened, more than 300 girls were in line, some of whom traveled several hundred miles for the chance to get a dress and matching shoes, accessories, jewelry and make-up.

Dresses kept arriving through the day from Operation Glass Slipper co-sponsors Use Again and A.W. Zengeler Cleaners, so those who weren’t in line when the doors opened were not out of luck.

Even mid-afternoon, girls interviewed by WBBM said there was a good selection of dresses in all sizes, and rooms filled of shoes, purses, make-up and more.

Dresses were separated by size on the third floor of Price, while other items were on the second floor. Each girl worked with a personal shopper, much like the upscale department stores, and if the girls needed tips in how to apply make-up, that was also available.

Those who were not on hand Saturday did not lose out. Use Again spokesperson and event organizer Rashan Grewaal said Price School will be restocked throughout the week, and next Saturday will be open again between 8 a.m. and 5 p.m.

Donations can be made at any Use Again collection box, in bags marked “prom,” and Zengeler will also accept dresses in all sizes. Girls wishing to participate next weekend must be juniors or seniors and have a valid school identification card.
