I went as corella deville from 101 dalmations one year, I watched the movie 5 times to get her voice down. I bought a long red cigarette holder and bought a fake cigarette. I had 2 stuffed dalmations slung over my shoulder (I know that is just wrong).
I had a fur coat that belonged to a friends mother that she loaned me and black and white spiked up wig.

I have fun playing evil characters....hehe
