This is the fashion now. Supriya Prithviraj used a similar kind for her wedding reception, so did Karthi's wife for her reception. I think the paloo and duppatta are actually the same material. It could be tied in such a way to make it seem like it's two different materials.
It is lehengs cum saree... The bottom of the saree will have grand work like lehenga...I think for this you need not fold to get fleets.. you need to just tie it like skirt.

Is that his grandson, Sunitha? I thought his grandson might be just 2-3yr old. Now I identified the lady standing at Dulqar's back is Surumi. Was wondering why she was not there in any of those photos.
