This could be expanded to countless places.
The generic idea of armor only is making me annoyed. Everything up to ear-rings down to rings, bracelets, shoes, robes, shirts, pants, socks, circlet, scarf, you name it.
Edit: Including Tatoos.
If need be, these items COULD be installed with bonuses, but I feel they should be strictly decorative, or else PKers will be dressed up ready to hibernate for the winter.
This would add a RP feel.
