Hi Michelle,
I have never bought a dress from Rainbowshiu from Ebay, but I have had her custom made two standard gowns for me. The first one I ordered was a design from her website with some of my own modifications. I love the dress, it is in very good quality. But I did pay extra to have the dress done with Swarovski stones and not the normal Korean stones. My second dress is a design from one of my friends' dress. I changed the color into pink, and of course, had it done with 60 grosses of Saworvskit Rose AB and Crystal AB stones. The cost is under 1,000 US. I will be recieving the dress sometimes this week, and I will let you know how it looks. But from my first dress from her, it's in Very Good condition. But again, this was custom made, not from her Ebay store.
There are several different that I get my dresses from. There is this one lady in NY who custom made dresses for me. She sells on Ebay too. She has made me one Latin Dress, and it is really nice. The price is about the same as Rainbowshiu. Other than that, there are two ladies locally who are both very good at dresses. One of them has been a designer for a long time, but new to the dance dress business, the other one is a current pro competitor in the US. Those two ladies charge more for dresses. PM me if you are interested.
