To make Franks top:

Use either a black t-shirt and cut the sleeves off, or use black tank top.

Cut a line straight down the front middle of the shirt. Make holes about an inch to an inch an a half apart from eachother with scissors. Use a long black string an lace it through them. Cover the rest of the top with sequins or glitter.

For his shoes

Buy a pair of thick heeled shoes like the ones Frank wears (close up in the elevator) and glue white glitter to the heels. Then put green sequins on them.

The rest of his costume, underwear, thigh-highs, makeup and cape are pretty self explanitory.
