I have been wondering the same thing. I found that if I fold the dress in half, that is the tulle folded up the back of the top it fits perfectly in the Priority mail boxes. I was thinking wrap all pretty in some tissue. Then pack it with a cute thank you letter with instructions on how to take your bow holder out and fluff it! The U haul mirror boxes sound great too. You just have to let your customers know up front how much it is to ship. I don't know if shipping parcel post would be cheaper than priority on something like this.
