M.M.
I don't but we had a formal father daughter dance for girl scouts last weekend and I found a dress at Goodwill for $8. It was in perfect condition and fit great.
I also have found other formal gowns for military balls at high end resale shops. THere is nothing better than finding a gown for $20 that you know cost $200 in the store.
Just something to think about .
Good luck.
