If you want people in other areas to buy your clothing and know about it try giving some shirts to people in other areas. Have them wear them to places and tell people about your site along with handing flyers or business cards out for you in exchange for the shirt or shirts.^_^ good luck. Hit me up via email if you would like.
Hannah is very honest 100% agree it will sell itself that way. Personally being in the silkscreen industry the t-shirts are just too basic for me.
