If you choose to get another dress, you still have time. Many of my girlfriends were in the same predicament and when they finally did find a dress, they got a rush order and it made it in time with a month to spare. This dress that you really want....how far out of your budget is it? Can you ki-bosh something else to allow movement in your budget to get the dress you want? I think you will have a problem finding a new dress only bc you seem so hung up on the other two. So if you really want that dress, I would either see if you can get it somewhere cheaper, get it made or try and find a knock off. You probably wont be really and truly happy until you have that dress. I really hope you can find the dress. Maybe you could post a picture of it on here....one of the ladies on here may have seen it somewhere else and possibly for a better price?
I wish you luck and hope you find what your looking for. Bc we all know its about the dress...lol
