I'm starting my own clothing company and I need an overseas manufacture to manufacture my t-shirts for a low cost.

How many 1000's of each style are you wishing to order. Most will have min of 1000 or so per size and color combination. Some have larger minimum orders.

Or do you need to just order plain T shirts in various colors that you will screen print or so something with , once they come to the US>

Hey Mr. Chuck thank you for the info Screen printing
