Cashstar Shooter shirt
This is another hub for getting tshirt manufacture. However unlike Gandhi Nagar Market, this is not much accessible. There are huge factories which cater to chains like Vishal magamart, Big Bazaar etc. However as per my experience with the Cashstar Shooter shirt moreover I will buy this manufacturer here, you can get tshirts manufactured by them provided you have a handsome quantity requirement. Business here are more upmarket.
