Help me find my wedding dress?

I tried on the DaVinci 1417 (a href="http://www.weddingshoppeinc.com/pr/Da-Vinci-8417/24058)" rel="nofollow"http://www.weddingshoppeinc.com/pr/Da-Vi…/a and loved it... or most of it. Now I'm looking for something similar (with the collar and the v-neck, don't worry about the beading, I'm going to replace it anyways) only as a halter with an open back. It might not exist - I'm not sure it's been out long enough for other designers to mimic it - but if it does, any help is much appreciated.
