Ok, so I kow a lot of people don't like the idea of buying a dress online, especially not from China, since you don't know how it really looks or the quality (among other things). I went to a wedding yesterday, and the bride purchased her dress at
www.weddingnova.com and it looked beautiful! As far as I know, they aren't designer knock offs. The dress was very nice. I helped her get dressed, so I saw first hand that the fabric quality was nice, the seams were well done, and it seemed like a very well built dress.
She told me the company even called her before making the dress to verify that she told them the right length.
Just thought I'd pass on the word.
