Dear Females,
Leggings are not pants. They are tights that happen to be a solid color. Leggings are called such because they are the shape of your legs. Exactly the shape of your legs. Please wear pants with your long sweater.
Love,
Me.
Either way you look at it driving at 40 mph and filing your nails, or your nail file grinding at 40 mph, it's just not a very good idea.
