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.

If you're stepping out with a squad this Halloween you can't go wrong with channeling the Chanels -- the sassy group of sorority sisters from "Scream Queens." Emma Roberts' character leads the clique, whose members only get numerical identities.

Recreate the girls' wardrobes by reaching for pastels, faux fur, feathers, and plenty of flashy baubles. Chanel #3 will need earmuffs because she's never without a pair of some sort -- fluffy, bejeweled, or whatever the occasion calls for. One of Roberts' best fashion moments comes in the form of a faux-fur vest from Brit brand Shrimps, and if you're lucky enough to own a Chanel bag, it will lend the perfect touch of authenticity to the Kappa president's wardrobe -- she calls Karl Lagerfeld "Uncle," after all.

And for the girl in your squad who would never wear anything fluffy or pink, there's newbie Grace, who tends to gravitate towards ripped jeans, varsity-inspired sweaters, and an inexplicable penchant for newsboy caps.

Kylie Jenner is having a moment to be sure; she's cornered the market on Snapchat and her just-launched app has eclipsed her sisters' in popularity, making her a no brainer costume choice come October 31. Plus, Halloween is pretty much every day for the beauty chameleon, who constantly changes up everything from her hair color to her lip size.

Go for a quirky-casual Jenner look with long aquamarine hair -- reach for colored extensions from the teen's collection for an authentic look -- a black sports bra, leggings, and Adidas' Yeezy Boost sneakers.

Alternatively, you can channel one of her more sultry styles by rocking long black hair, a high-cut swimsuit, expertly contoured makeup and pouty nude lips. We suggest avoiding the controversial shot glass lip-plumping method that Jenner helped popularize earlier this year and instead adopting one of these clever -- and safe! -- lip-plumping hacks.

No one (with an Instagram account) will question who you are.
