Having worn my current ones a lot in the last year, I'm looking for somewhere to get t-shirts with prints on in strong (non-pastel) shades. Just for wearing with jeans and trainers.
I have a few band t-shirts and am thinking of that kind of style, but not necessarily advertising my musical preferences 
. Preferably good thick material and bonus points for eco credentials. Long enough to cover the top of my jeans too!
Where can I look?
