Used Prom Dresses

Where can I donate prom dresses in the Indianapolis, Indiana area?
I have several gently used bridesmaid/prom dresses hanging out in my closet. I would absolutely love to find a place to donate them that gives them away for FREE to underprivileged teenagers, so they can attend their high school prom. Any insight or ideas?
Most schools have a such a program - you can check with North Central and Ben Davis to start - I THINK Broad Ripple does this too.
Cool of you to do this!
