drawing blood

Stupid title I know, but I'm running on empty here. This is a drawing of what I want my costume to be. My interpretation of sexy vampire, on little to no money. I have a shirt that will work, and the duster. (Is that what they are called? I don't have a better word for it. Again empty.) I need to find a skirt. I'd like a floor length one, but if I can't find it do you think a tea length skirt would work? I'm also (hopefully) buying vampire fangs. Super excited about that.
Since I have to (get to) dress up for work four days next week, I have a couple costumes I'll be wearing. I think I'll wear my Greek Goddess costume from last year again, but the hair, make-up, and accessories will be better planned out and executed this year. Then I think I might go in scrubs a couple days. Who wouldn't want to wear comfy scrubs to work?
