The reality star looked more glamorous than spooky as she dressed up as the film's lead character ballerina Nina Sayers, aka The Swan Queen, played by Natalie Portman.
Louise wore a strapless black dress complete with ruffles near the neckline, adding a dazzling diamante tiara.
Ballet dancers usually whip their locks into a bun, but Louise opted for a chic fishtail braid swept over one shoulder. The starlet recently chopped her ombre hair into a shoulder-grazing bob, so her plait must actually be a sneaky clip-in piece. Get the look with this clip-in fishtail braid, £29.99 from Beauty Works.
While we like her cute outfit, is was her make-up which really stole the scene!
Louise flaunted kohl-rimmed eyes, with eyeshadow swept from the outer corners of her peepers right up to her hairline, just like Nina.
She kept the rest of her make-up low-key before upping the drama with a fierce black lip and matching talons.
Now black lippies aren't easy to come by, so if you fancy recreating this look get your mitts on Illamasqua Lipstick in Pristine, £16.50, a pure black with a matte finish.
Go on, we dare you!
