The Caesars Palace crooner is also quite easy to imitate. The first step, fedora. Second step, tux. Third step, douse yourself in cheap cologne. Mascara and English accent optional.
A classier Vegas take on the usual skank costume. You can wear any glamorous dress and heels, but to capture the essence of Holly you’ll need two things: blonde hair and big boobs. Wait, does that count as three?
This also is one-fourth of a great group costume. Throw in your gay best friend, a ditzy brunette and your blonde understudy and you’ve got Holly’s World!
Also an awesome group costume, but perfect for lazy people, like, sweatpants lazy. Black hoodies, black sweatpants, white gloves, white mask and - viola! - Las Vegas' best dance crew. Then just pop, lock and drop all night.
The raven-haired songstress of Absinthe (returning October 21!) is as glam as they get here on The Strip. Think classic, Bettie Page pin-up girl when it comes to the hair and makeup: jet black wig, dramatic cat eye-eyeliner and red lips.
You can go two ways with the rest of the costume and still look like a bombshell. You can go Mad Men retro with a dress from the Bettie Page store. Or, if you're more fearless and risqué, complete the look wearing just a pair of pasties, panties and stockings held up with garter belts. Meow!
