Don't do it. I worked at a bridal salon for 2 years and helped some 200 brides find their dresses. A number of them had originally ordered dresses online thinking they were getting a real bargain, and were terribly dissapointed in what they got. I'm not saying that happens to every girl, but I've bailed out enough brides at the last minute to advise against it. You should always order from a salon that allows you to try on the gown first and is an authorized retailer of that designer. You can find out if the store is authorized on the designer's website. If it's not, look elsewhere.
