As said in above response both the markets are very good for the whole sale shopping for various occasions like wedding or any other ceremony. You can also visit Sarojini Nagar Market to buy some cool stuff for the youngsters as most of the youth of Delhi comes to this market to buy fashionable clothes in bulk.The prices here are very cheap and the stuff is really cool. You can buy clothes, accessories, shoes and sandals, bags, purses and many more.
As I think, there are many whole sale market in Delhi. Specially for clothes, there are different different markets for different different clothes.
Like, Chandni Chowk, situated in old Delhi, is for ladies & gents clothes. Seelampur, situated in east Delhi, is for Jeans and exports clothes(Printed & Graphics clothes). Tank Road, situated in central Delhi is specially for Jeans. Tank Road is Asia's largest wholesale market of garments. This market is famous for cheap Denim clothes. Gandhi Nagar, located in east Delhi, market is for ready-made clothes . Moti Bazar is for Shawls and pearls. And many more.
