Clarisse la Rue from the Percy Jackson and the Olympians (PJO) books. Most of the costume is store bought in one way or another - I got the very inaccurate camp halfblood shirt from Borders (I'm going to make my own before I wear it next, dang it), and the fatigues were also bought at goodwill. The shield was from Michael's - a cheap little foam toy I painted up better, and I painted all the beads on the necklace.
