So I have fallen in love with a dress, but it is out of my price range

Does anyone know of similar dresses/designers to the Watters Greta gown? (
http://watters.com/Product/WattersBrides/1049B) It is an all-over lace fit-and-flare with a keyhole back. I LOVE the shape and the keyhole back but I would ideally like to pay $1,000 or less.
Any suggestions would be greatly appreciated!
(Also, if anyone knows of ways/places to find Watters gowns discounted, that would be helpful as well!)
Thanks
