Dress Website

Anyone have any good websites where you can put in what you are looking for, in detail, and find dresses out there? I'm having such a hard time. I tried searching for create your own dress websites, etc. I am sure the dress I want is out there...I just can't find it.

Also, I tried on a dress at one location that removes the designers from them. I can't locate the dress on line. I tried it on 2x already but would like to see some pics of it on people. Any suggestions?

TIA!
