|I am your shield; I am your sword|
This photo is possibly the most perfect Cortana cosplay ever
The blues are awesome, the face is pretty and the costume is subtle enough to not be so obvious that it's a roughly made onsie.... what do you think - is this player's version of Cortana better than these keen lasses?
For those not in the know, Cortana is a popular character from the Halo franchise. She's expected to play a big role in Halo 4, indeed it's known she's going to go rampant.
Found with another image of the curvey Cortana here.
