Update: I sent the pic of #1 with curves to one of the knock-off designers and China. I specified that I wanted a sweetheart neckline. They said no problems and quoted me $150, including shipping. Their reviews are great so I am going to go for it. They sent me pics of a similar dress they've made and I like it as well so I think I have made my decision. Although, I have had my measurements in hand for 2 weeks and have yet to send them over!
Thanks again for the feedback!
