Because I'm tall and I'm not comfortable with how short it makes skirts even when they're not designed to be short. Also because I don't tan, like, ever, and my legs are pasty white and pretty much glow in the dark. Also because I have KP (keratosis pilaris) and even though it's quite common I still hate how it makes my legs look (it's worse on my upper arms but I'm not that self-conscious about them?). Oh, and also so that I don't have to shave every other day. Nobody has time for that **** when you can just wear tights instead.
