Hi! My wedding dress was pretty much wrinkle proof. It is a replica of the Jessica Simpson dress so it was all lace with beading, sequins, etc. Very heavy and just wouldn't wrinkle. So, I decided the best option for me was to take it on the plane because it would not wrinkle and I was scared to ship it. I did have a friend attending the wedding who lives in Clearmont whom I shipped my big boxes of wedding decorations, gifts, etc. to but my dress and accessories I kept as close to me at all times as possible.
It is really going to be a matter of what you feel comfortable doing. As others have said you can definately get it steamed and I have heard nothing but good things about Carolyn Allens so I wouldn't worry about that part at all. Good luck in your decision and keep us all posted.
Have A Magical Day!
