I don't per se care what people wear (unless it's women in hats, which is to be encouraged, because you know, oh happy thoughts). That said, having to dress up does make cycling seem a bit harder than it ought to be, and require special uniforms. You have to commit. It's a bit like fetish wear, really, you can't just make it up, you've got to go the whole hog (not literally, that's a fetish too far). What, I'm wearing leather socks isn't going to cut it. Well, possibly if that's all you're wearing, it might.
