Prom can cost a high schooler hundreds of dollars.
The most expensive item for many girls is the dress.
Affording the prom could get easier for some girls this spring thanks to some students at Interboro High School.
They are now selling those new or gently used dresses for only $10 at a prom dress drive on Saturday at the High School.
All the proceeds go to the Children's Hospital of Philadelphia's Autism division.
