My wedding is in 19 days (omg...) and I realized the train of my dress is not completely "ironed" out. It has a few crinkles that I definitely don't want on the day of. I don't know how long it takes them to steam it, or when is an ideal time to have it back. How should I hang/store it when they give it back to me. I don't want it getting dirty or wrinkled again before my wedding. Thanks!
