It depends on the material. Most synthetic fibers or even natural/synthetic blends are made nowadays to not shrink. If it is made out of a material that shrinks, there's always good ol' fashioned outdoor clothes lines. And if you think a simple t-shirt will shrink, try sticking a wool sweater in the dryer. It ends up being doll clothes! lol

I think the point though is that you could do this for any of the shirts. McCoy is my guy, so blue is a good one. :)

But i don't think i just wanna be a Star Treck person :P I am more into sci-fi armored weapon suits.
