Looking for a Ready-to-Wear Saree

My best friend from Salem is getting married and really wants me to wear a saree for the wedding. The only problem is i have never worn one before and have no idea how to drape it! So, I’m thinking of getting a ready-to-wear saree. Does anyone know where I can find one, either in a store or online? I’m looking for something appropriate for a traditional Tamil wedding, not a party-style saree.
