Saw this on WXYZ last night, and it is an amazing story. The dresses looked lovely, and all the money goes to the Cancer Support Community of Ann Arbor. They probably don't have a very large selection, since all their dresses are donated. Not clear about alterations either. But it IS for a good cause!
