I found this neat graphic on the Osprey Packs blog.
You've gotta love some of the questions on it: "Ever worked as a bike messenger or dreamed of it?" "What's your favorite kind of equestrian event?" "Which are you more likely to consume while riding?"
But my favorite question is the one at the top of the "chain": "Are you wearing a top hat?" Honestly, I am not, and never have.
I've worn all sorts of things--and very little of anything at all--while riding my bike. And, before I started wearing helmet, I sported all manner of headgear, from bonnets to berets--and, yes, cycling caps. But no top hat. Or spats.
