I don't know if it's just an AS trait or not. I'm NT and hate wearing make-up. It feels like wearing a mask, and I hate the sensation of presenting a false face to the world. I simply am what I am. My 16yo is the same way, and she's NT, as well.
I think it may be a family trait for us. None of the women on my mother's side of the family wear make-up. We're all very conservative in dress, jewelry, and the like. I think it's nurture on our part, not nature.
