Stockings to go under a halloween costume.

Okay well I’m going to be a vampire for Halloween but I do not want to buy the costume. I want to make it from things from different stores and make it look really real. Nothing cheesy. Okay well I already have good ideas but I need help on a couple of things.
First I don’t know what to do with my hair. I’m going to put white streaks in it but I don’t know how to style it, so help with that please?
Next I need help with the clothes.I’m thinking of wearing a black, laced, corset top that I could get from Hot Topic or some thrift store,but I don’t know what to wear with it! Like maybe a black skirt..but I dunno if they’ll still look vampire-like. I wanted fishnet or just regular stockings with it and black heels.I’m not so sure if I should wear a cape or if that would ruin the type of vampire look my costume is going towards so far. So I know what to do with my make-up (heavy eyeliner, fake eyelashes, heavy dark gray eyeshadow on top-bottom, red lipstick, dead white foundation, no blush, maybe a trickle of blood coming from the lip, and probably fake fangs.) I really want this too look real and scary, and nothing that’s already been made at a store. Sexiness of it doesn’t really matter as long as its not completely lingerie disgusting.

I want to go all out this halloween with a very sexy costume, to wear to a party where they give out prizes for sexiest costumes. I always get compliments on my legs so I want to wear heels and show a lot of leg. I was even thinking of a garterbelt and stockings. Any Ideas on costumes ideas and where to get one online would be appriciated.

1. Pin Up girl – no specific store bought costume. I would go the lingerie route and wear a corset, ruffled shorts and stockings. Maybe not true pin up but whatever. Then hair probably this wig:
