She's interesting to look at. She's different. In my opinion it's the idiosyncrasies that make a person especially attractive. Keeley Hazell, Kelly Brook, Lucy Pinder... they all look the same to me. Curvy, brunette, big breasts. That's fine, i'm not saying they're unnatractive... quite the opposite, they're very attractive indeed but there's nothing interesting about them. Nothing makes them stand out from each other.
Lily Cole, however, is attractive because not only is she pretty, but she's different, and interesting to look at. Perhaps there are a host of imperfections, but that's all good. I'd have to feed her up a bit though.
And no, I'm not an especially attractive guy and i wouldn't turn Keeley Hazell down if she asked nicely.
