For hair, either get a long, Cher-like wig with blunt bangs or flat iron your own long, dark hair.
For makeup, go heavy on the eyes, light everywhere else. Apply a cat-eye with black liquid liner on bottom and top lids. Apply heavy eyeshadow and top it all off with dramatic feathery false eyelashes.
For shoes, you'll want gold sandals. Good luck finding some in October. You can also spray paint sandals with gold spray paint.
