I went to a bridal expo a few months ago. The cake was great, but everything else was completely not for destination brides. I did talk to a local dry cleaner about dress preservation after the wedding. She mentioned that they have this new thing specifically for DW brides to carry on their wedding dresses. I searched today for more information and found the link below. I need to call my airline and see if the size is going to work, but I just thought someone else out there might like this information too!
