United In Unif
For general t-shirt awesomeness I do so like UNIF clothing.
For anyone wearing metal style tees just as a fashion 'statement', then this might seem a tad tired to you now, but for those of us perpetually about to rock, metal style is always a winner.
I have the 'Jesus Saves, I Spent' tee and I do chuckle whenever I wear it, sadly enough. UNIF don't just do t-shirts though - their collection includes jackets, shirts and shorts.
