Absolutely no icons, brand labels, or stuff with words.
Black cargo pants, with black suspenders, a black shirt, a black over shirt, a black hat, black shoes, with black socks, ala black, upon black, on black, with a side of black rice, and... black.
Not emo, and not goth (though I used to subscribe to that moniker.)
One of my favorite outfits aside is a black button up shirt, black slacks, and a black sports jacket. (*looks very shiny*)
