**I too have my Nikkah in Dec IA, and I have the same problem...
But then I decided to wear saari on the function (lets see how it goes) and if I wont find any then anarkali frock, with embroidery/kaam on the bottom instead of it on choli... or simple shalwar qameez, with either ghaeray wali shalwar or choridaar pajama.. but that WONT be definitely shalwar qameez or lehnga **
i have seen brides wearing white or red color dresses on nikha day i like the white idea.btw wht color u have decided:)
