Wow, I had no idea that tan lines were such a hot topic. Or rather, that some people think they are hot and others think they aren't hot at all. I guess if a girl has extreme lines, that's dumb because she's spending all day in the sun and not doing anything interesting. Farmer's tans are cool since they're just "normal" and most people get them from playing sports or working outside, which I respect.
I guess I don't get tan lines on purpose just to be sexy... they just happen. I often get them, since my Thai half tans quickly and my Icelandic half keeps the covered skin very pale. When I was in Africa this summer, my face, hands, and arms got really dark, but the rest of me was unexposed because of the local conservative dress (no shorts, etc). So I have some weird lines now, but I doubt ktspktsp cares much either way.
