I am not sure of the authentic silk-ness of their dress material. I was visiting Bangalore and wanted to do some shopping. I bought, what I was told, was pure silk by the meter from them at Rs. 275 a meter. Expensive, right? Once I got back to my home town, I did the classic silk test--burning a thread to see if it smells of burnt hair and if it crumbles. The cloth failed both tests. It turned into a plastic, gooey ball that smelt like burnt synthetic material. I feel like a fool that I did not test the material in the store itself!!!
I also read in one of their ads that all products carry the "silk mark." So please beware before you shop.
