When I go to Chennai I hang out in T Nagar area..period!!!! RMKV had some awesome collections. Then even Chennai Silks. I visit Kumaran (both of them) Pothys, chennai silks, and RMKV. for both sarees and dress materials.. I prefer my salwars to be stitched coz somehow readymades and me dont get along well!!! 😃 I heard sundari silks is good too also Prashnthi for silk cottons.
If any of you like fashion jewelry..go to Narayana pearls for silver -gold plated jewelry or jill-mill for costume jewelry.. I love those and generally freak mout on those! 😉
