I really enjoyed playing the Assassin's Creed series. Personally, I liked Altair better than Ezio. (Ezio is pretty stupid, imo.) But I have no confidence in pulling off Altair. But there are a few female assassins in Assassin's Creed 2. A couple who are not "courtesans" even! Iltani's outfit had a neckline that was a bit too low for my taste so I settled on Amunet.
I made this costume before the Fall of Reach: Bootcamp comic came out and based it on the description in the book.
The appearance of a Greek goddess: barefoot, wrapped in the toga, motes of light dancing about her luminous white hair and holds a clay tablet in her left hand.
