I've been thinking for a while that a "Mask" clothing layer on the avatar head, like a shirt, jacket, pants, etc would be useful.
This would allow residents to wear different kinds of facial make-up and scars without having to spend another 1000L on a skin with a different face.
I figure a lot of skin-makers are opposed to this, but hey, you can make make-up layers and sell them at jacked-up prices if ya want,. *shrugs8
