The costume: Miley Cyrus 
She's twerked her way onto America's TV screens, and now Miley Cyrus is one of the most covetable Halloween  costumes of the year. And lucky for you, the beauty that goes along with it is fairly easy to pull off. All you need is a foam finger . . .
Hair and makeup: Oh, those buns. They're simple and easy to do yourself. Just part your hair down the middle, sweep the sections up into two high ponytails, and coil them into tight buns. Make sure to add a healthy dose of hairspray or gel. Swipe on some bold red lipstick, add some false lashes, and you're all set.
What to wear: Yes, that bear leotard is available online, and you can pick one up , but we're thinking modesty might be the best policy. Pick up the tank top version, and pair it with whatever bottom you'd like. If you can't get your hands on a foam finger with stiletto nails, slap on some press-on nail art, and you're set.
