It took me some days to find the right place to buy Manipuri silk items in Bangalore. Just in case you want to buy some Manipuri Silk (Phanek, Sarees etc) in Bangalore, Avenue road has got some nice shops. My parents bought some from Hi-Silk; although I don’t have a clue about the clothes, you can try there [maps: http://www.panoramio.com/photo/58175789]
