I answered to the question “Where to buy silk sarees online?” at WhereToBuyOnline.in recently. I thought it’ll be good to share the answer here too.
RmKV is a very old and popular store for silk sarees in Chennai. There are few other good silk saree stores in Chennai like Nalli, Kumaran Silks, The Chennai Silks, Pothys etc. They all have very good collection on silk sarees and other sarees.
