Ever wanted that Devil look that just attracts peoples attention? Looking for a sexy costume for halloween? You've come to the right place.

[edit] Steps

Dye your hair white, curl it, and bring it up. For a bit more effect, but white beads in your hair. Pull it back with a thick red ribbon, and add some gold sparkles to it. (Optional: Put some black devil horns on your head, and maybe wrap a black ribbon across one of your eyes.)
Try to get a dark tan. Also, you can put in blue eye contacts. Put on light makeup across one of your eyes so it looks like a scar, and put on red lipstick. If possible, put a fake cigar in your mouth.
Make it look like your magical. For instance, try having white doves as a pet.
Wear a black tunic, and weave gold thread into the sides. Get a red tux and wear it underneath the tunic, and weath gold thread into that as well. Wear a black tee shirt underneath this all, but so the rim doesn't show, make sure that you wear a white scarf.
Wear a white layered skirt.
For accessories, get a ruby ring and place it on your finger. You can also wear a fake sword in one hand and some playing cards in the other. Fix on a black devils tail if you wish.
For shoes, wear black boots with gold buttons on, and red folded socks.
To complete the look, wear a blood red brooch.
