I am not opposed to all bandanas. There are certain people who wear bandanas (i.e. tennis players Roger Federer and Rafael Nadal) who look perfectly fine and can pull it off. There's a difference, though: they wear solid-colored Nike bandanas that are folded up into more of a headband. The headbands are functional.Then, there's the paisley bandana that has been around for quite some time. It's like a handkerchief, but is usually folded in some way in order to be worn on the head.
Yesterday, I saw a mid-20s guy strolling down Broad Street sporting a paisley bandana on his head. I immediately looked down to see if he was carrying a motorcycle helmet (motorcycle riders are allowed to wear them), but he wasn't. I looked at my watch for the date -- maybe he was dressing up for Halloween? Negative.
It was at this point that I realized you're going to look very silly wearing a paisley bandana on your head these days. So, to sum up, unless you're a pirate or a cowboy, the paisley bandana should be off limits.
