If worse comes to worse, and Penney's won't take it back or give you credit etc, there are some organizations that will gladly accept gowns, used or new, for girls who can't afford them for proms etc. I gave some away to "Fairygodmothers" (I forget the website full address) but thery're here in Pa, near me, and you can mail it to them. I worked part time in a department store in the dress department, and people would return summer dresses and gowns in the winter. Some worn, some new, and because the customer is always right, we always took them back.
