Where is a good place to buy thick, form-fitting leggings that won't show my underwear? Or, barring that, thin, form-fitting pants? (No bootcut, or flares; have to be form-fitting right down to the ankle.) I'm revamping my outfit for the charity zombie walks I attend (as a human survivor / zombie-hunter), and I've decided to go for pants this time around. (Let's face it, booty shorts and fishnets photograph well, but they're torture when the colder weather starts, and I'm kind of a pansy about that.)
Also, cheap = awesome. I'm really not down to pay $50 for a pair of pants or leggings. What brands do you guys like?
