What kind of jeans/pants/skirts make your legs look skinnier?

I'm not fat, so don't tell me to "eat better" or lose weight. I DON'T want to lose weight. I have a miniscule waist, my ribs poke out, and if I lost weight I would look freaky. I just want to make my legs look skinnier in comparison to my waist (big hips). What kind of clothing would do this?
