PHOTOS: Become Your Favorite Star for Halloween!

Though costumes usually consist of the skimpy and scary, RadarOnline.com dove into star style for you adventurous bunch that want to dress as your favorite celebrity for Halloween!  Take the following tips from these stars' actual stylists!

For Katy Perry, her style maker Johnny Wujek tells us that an essential element for Katy's look is "something over sized, like an oversized Ham costume."

All kidding aside, Perry is a huge fan of larger than life accessories. In the past year, she's performed riding giant bananas and tubes of lipstick. For a look like hers, pair a dark eye with big hair, girly looks with some pop culture references and tons of touches: bunches of fruit, dice or even your very own Russell Brand!

For the hard chic of Rihanna, her stylist Mariel Haenn told us there's a simple formula for being Ri, and it starts with "a structured shoulder, a rocker boot and a red lacquered lip."

From there, ladies make sure you cut or pin your hair into her pixy cut with exaggerated bangs with blonde accents. For a super-current Rihanna look, throw in a studded eye patch.

For the throwback glam of Christina Aguilera, follow the lead of her style guru Simone Harouche--vamp, vamp, vamp!

A platinum wig and blood-red lip should start you off right, followed by  flirty prints like leopard, cleavage-highlighting mini dresses like Herve Leger's popular bandage and some super-high stilettos.

A microphone and some giant faux bling should button up the Xtina homage perfectly!
