Beautiful white formal gown

This was worn to a military ball. I am looking to trade it for the next one in attending. I had to alter the straps myself. Not the best job but they're in the back so they're not noticeable. Truly beautiful can even be used as a wedding dress or and prom dress. In very good shape. I wear pants size eight but because it's a wedding dress it runs incredibly small. I wear an 8 formal dress. Trade value $400
