Hair:
Dreadlocks (PLEASE!!!)
Corn Rows
Braids with beads on the ends
Mohawk (several different styles) If hats are an issue, it neednt be tall, or a mohawk can be a hat instead
Eyes:
Colored eyes!!!!!
Hats: (I Think Masks and hats should be separate, and both possible on a character. However, I see some items cover both the face and the head, making this difficult. I think these should be considered masks since they appear to leave room for hats. )
Native american type headdress
Rasta
Beret
Coonskin
Masks:
Sunglasses and Eyeglasses, different types!
Monocle
Mustache and beard sets!
Pipe
Animal Masks (that give animal faces, not just animals on top of your head like a hat)
A Vanity idea... I would sometimes like to see the whole avatar while in the vanity in order to make sure the avatar matches the outfit.
A Wardrobe idea... How about tails?
