The Best-Dressed Celebs This Week (Holiday Edition): 12/27/13

Fancy galas, major red carpets, and awards show appearances usually fuel our most stylish stars list each week, but today we're focusing on living room Instagrams and holiday party snapshots. Here's who killed it this Christmas.

Happy Holidays from Pia Mia! You can never go wrong with a good snowflake sweater.

Jess Alba posted this adorable family pic on Insta and the kids look cute and all, but we really couldn't stop obsessing over her red leather skirt and crisp white top. Such a good look.

Kylie went the gothic route for Christmas Eve, obviously. Her grams doesn't seem to mind though.

Rihanna rocked a black tank and festive long skirt for one of her 7,457 photos she took over the holidays. We like her consistency though.

Khloe K and Kendall Jenner killing it in matching high slits. #NBD

Nicky Hilton went schoolgirl-chic in a tartan plaid skirt and black tights.

Vanderpump Rules star Scheana Marie also got into the holiday spirit in a Santa hat and pretty metallic dress.

It's never too cold for crop tops according to Lucy Hale! Here she is posing with her "4 favorite boys" as she calls them.

We heart you Kelly Osbourne and your leopard jacket, purple hair, and fun balloon, too.

New mom Fergie rocked a silver blazer and bold red lip to celebrate Christmas with hot husband Josh Duhamel and their son Axl, along with her parents. That post-baby bod looks good on you Fergs!
