Dragons New Uniform T's Now at Official Dragons Website
The 2012 uniform T-shirts are now available for purchase here.
Looks like they are standard T-shirts, no piping like on the uniforms. Their site says that pro-style uniforms should be available sometime next month. Unfortunatly, they don't ship outside of Japan, so unless you live in Japan you will have to go through an intermediary to get one or anything else off their site.
