Because I'm bizarrely convinced that my legs are weirdly shaped, I almost never wear leggings. When I look in the mirror, I understand from an arbitrary perspective, my legs are probably normal, but of course the normal vantage point that I use to stare at me own pins is from the head down. Which means that all I see is a cone -- extremely large thighs that taper down to skinny little ankles. As I was saying the other day, I'd trade in one cup size for two inches on my legs any day, no thought required. (And to clarify, that's vertically, not horizontally, I can accomplish the latter with relatively little effort and a lot of burgers.)
For those of you who do love the legging look, then Black Milk Clothing is the place to go. Some of their tights are so damn fierce, I'd consider adding them to my closet, except that I've had disastrous experiences buying leggings that don't fit, so I'm scarred for life in that respect. The ones with grommets that look like the long-lost relative of the Ann D lace-up boots are my faves, but the porn-starness of the latex leggings are also particularly enticing.
