I'm very bad with remembering birthdays, and usually, it's difficult for me to remember what someone is interested in until I have a mental picture of it. (If it's an anime, I remember it after I've seen it, if it's a video game, I remember after playing it, watching someone play it, or looking at the box.) Of course, if they talk about it a lot, I remember that way, too.
Yes, I usually remember people by clothing better than by face (main reason why I couldn't tell most of the girls apart at my old school; they all were wearing the latest fashions). Especially since one of my friends wears a bright, red hat most of the time. If she isn't wearing it, I find it almost impossible to keep track of her in a crowd, even though I can't think of anyone who looks remotely like her.
