Thinking about glamours today, and wanting a somewhat more tribal theme to my mage jobs, I realised there isnt much made of bone, but plenty of animals that (or could) drop bones.
Here some ideas:

Tank:
head gear like this: http://img3.wikia.nocookie.net/__cb2...Armour_Set.jpg
body like this: http://img.4plebs.org/boards/tg/imag...6160837861.png

DPS:

body: http://hydra-media.cursecdn.com/path...e1b22b6088c809
Or maybe something a little more war-torn.

Magic DPS / Heal:
