I am looking forward to buy a J Crew BM dress to wear in my sister’s wedding in April I’m her only as an attendant, but the one I really love is a 6 from a past-season, that they don’t sell anymore. If anyone has first-hand experience, here, that can give me a better idea of how they fit? Has anyone bought their wedding dress from J Crew, or their bridesmaid’s dresses? I know you can return the dress to the store if it doesn’t fit, but what about alterations? Can you get them done at the store?
