Sleeveless black concert t-shirts and ripped jeans are evergreens.
Of course, I almost always wear collared shirts. It is rare that anyone will see me in just a t-shirt.
The shirt and pants work.

If he is going to have a patterned tie with a patterned shirt, they need to be different patterns, different sizes, or preferably both.
Plus, a black tie would probably not be the same black as his pants, thereby clashing.
