My sister is having a beach wedding next month and the changing room situation is kind of iffy. The beach has wet, sandy changing rooms. I can't avoid getting sandy and a touch muddy just changing back into my street clothes in them, so I think it would be a bad idea to try to dress a bride and her wedding party there. Everyone can dress at home and arrive already dressed, but the bride's royal blue satin dress wrinkles very easily. So I think our solution is to dress her at home and spray her dress with a wrinkle-releasing spray at the beach. Do you know of a good one that won't leave spots?
