I've never liked thick legs, but when I was younger I had a thing for thick ankles (not cankles, but thick ankles). Not sure why, and I haven't thought about that in years.
Here are a few responses to some of the things already mentioned:
Eye Shadow: The "smokey eye" look seems to be in fashion these days. I do like it, I'm not sure why. You'd think dark pigment under the eye would look unhealthy, but for some reason it looks hot.
Feet: I've never had a foot fetish, but I've always thought that female bare feet were suggestive of nudity, and that is part of the attraction. I'd prefer to never have to see a male's feet, thank you very much. But a woman in bare feet is often kind of sexy.
Glasses: I don't see how glasses hurt a girl's looks at all. Definitely not these days when they have more styles available. The old saying "Boys never make passes at girls who wear glasses" was from a time when there were very few designs to choose from - women's "cat's eye" glasses or whatnot.
I always thought it was really stupid when you watch those movies where they take some gorgeous actress and try to pass her off as homely just by putting a pair of glasses on her. And then later in the movie they take her glasses off and *poof* she's pretty. As if you couldn't tell all along.
