Come to think of it, if you ordered it from the shop & they put your order in with the designer on the same day, the designer should have said at that time that the dress was being discontinued & they could not honor your order. I would think that this would happen right away. So how long ago was it that you placed your order that they are getting back to you today with this news?
On the other hand, with the same circumstances, I would think that if you already ordered it, and the order went to the designer, why would the designer not honor his/her committment to have your dress. It would seem that when something is discontinued, it only affects future orders, not orders already placed. Do I make sense here? LOL
