Full on sass or complete a$$?
Back in the 90s I dated a guy who wore a scarf. It was black with some sort of pattern and extremely worn out. Sometimes he wore it with a tee shirt, other times he wore it with a tank top and vest. When he really wanted to strike a pose he wore it like a pirate, argh. Usually, he knotted it like Stefano Pilati up there on the top right. I thought it looked damn hot. My friends, on the other hand, thought he looked like an a$$.
