Expect to see 50 shades of draped grey this Halloween with people mimicking the unforgettable nun from the season finale of "Game of Thrones." You'll need a holy woman's robe and habit -- a grey scarf will do in a pinch -- as well as a handheld bell that you can clang incessantly as you judge people all night long (a costume perk that's perfect for those who love calling people out on party fouls). Part of a couple? All the better, as one of you can be the Cersei to the other's holier-than-thou-nun. Simply grab a flesh-colored bodysuit to channel the disgraced royal on the world's most notorious walk of shame.

Cookie's style is all about opulence, so dressing up as her for Halloween will give you the chance to pile on your fiercest gear. Leopard printed, body-skimming dress? Check. (Faux) Fur coat? Check. Sky-high pumps? Check. When it comes to Cookie's style and attitude, more is more. This is one Lyon that will roar loud enough to turn heads at any Halloween party.

The hotly anticipated Pixar release brought us Amy Poehler as the (perfectly-cast) voice of Joy. To pull off the upbeat character's pretty pixie cut, you could reach for a wig or convert your existing 'do into a faux pixie.

But whether you're pinning up long locks or working with an existing short cut, you can achieve Joy's signature blue hair color with a few swipes of a hair chalk product, such as Kevin Murphy's Color Bug.

Reach for a bright yellow liner such as Inglot's Matte Collection AMC Eyeliner Gel in 84 -- a notice-me neon shade -- as a nod to Joy's glowing aura. Finish off your costume with a fit-and-flare green floral dress and your look will have you jumping for -- wait for it -- joy.

Naturally upbeat folks can't go wrong with Ellie Kemper's eternally optimistic Kimmy Schmidt character, who just can't seem to stop smiling despite the fact that she's been locked in an underground bunker for years. Recreate Kimmy's signature colorful getup by reaching for hot pink skinny jeans, a flowered button-up, bejeweled high-top sneakers, and the clincher -- her sunshine yellow cardigan with butterfly patches. Points if you've got the ginger waves (real or fake) to complete the look.

For a clever way to recreate Furiosa's gritty, dirty look, apply coffee grounds or GlamGlow's YouthMud Tinglexfoliate Treatment on your forehead. If you're not planning on shaving your head à la Charlize Theron just for Halloween, you could always wear a black stocking or bathing cap to mimic her look. Dark-haired gals also have the option of simply slicking their hair back to create a buzzed effect. As for your outfit, give a torn-and-tattered tee a second life, and stack on some belts.
