where to buy nice t-shirts?

I think I know what kinda tees you mean. Just off the top of my head, and thinking what shops there are near me, I would say: Cotton On, Just Jeans, Jeans West, Edge Clothing, General Pants Co. Hth

Go down Brunswick St and check out Neo Tokyo, Tomorrow Never Knows and there's a few others I can't think of the names off the top of my head.

Esprit have got some summer stock in now. They have alot of plain and printed Tshirts and 3/4 sleeve Tshirst as well.
It also depends on what you want to spend. General Pants and Co usually have some pretty funky Tshirts.
