I fell in love with a picture of a Watters dress but at the time only had the picture and had no clue where it had come from or who designed it. I recently went into a bridal salon and the consolant amidiatly recognized the dress and I was able to try it on, this dress that I never though I could, I can't tell you how that felt. Needless to say the price in the salon is way out of my budget. I have found the dress on may whoelsale site but am unsure if they can be trusted. If I was to order it from one of them would it be the same dress or a nock off?
