The TOWIE star, 22, and her sister Billie, 23, decided to make their Minnies Boutique festive celebration a bit different by getting the staff to wear wigs.
Both sisters shared pictures of their fun night out with their Twitter followers, and Sam wrote: "Had such a good night with my minnies team x x."
She wore the boldest wig of all from Wonderland Wigs, teamed with diamanté kitten ears and a spangly silver dress perfect for the festive party season.
Billie, meanwhile, wore a more natural auburn wig with feathered fringe and a navy blue dress that showed off her famously curvy body.
Posing in a snap with her extremely youthful-looking mum Sue - who runs their Brentwood store - Billie wrote: "Me and my mumma @MinniesBoutique Christmas party..."
Friend and fellow TOWIE star Gemma Collins also joined the festivities, although she chose NOT to wear a wig. She arrived at the party looking very loved-up with boyfriend Rami Hawash.
Sam's love life isn't as settled, however, after recently splitting with ex-fiancé Joey Essex. We're sure she won't stay single for long, though!
