If it wasn't already obvious that Kate Hudson and Goldie Hawn have an unbreakable mother-daughter bond, the pair showed just how tough they are together on Thursday night at Hudson's Halloween party. Along with a group of friends, the duo dressed up as the gang from the hit TV show Sons of Anarchy at the Los Angeles bash.

"Mother of Anarchy is taking her daughters to a little party.... #HappyHalloween @hudsonjeans_pk #hudsons #partytime," Hudson captioned a photo of the group in head-to-toe leather that she shared on her Instagram account (above).

While Hawn was clearly the leader of the pack, Hudson's revealing ensemble took center stage. The actress showed off her toned physique (can you believe she's a mother of two?) in leather short-shorts, a cropped and studded leather halter, thigh-high boots, garters, fingerless gloves, and a hat.

Hudson is clearly a big fan of All Hallows' Eve—the actress began her celebrations last week when she posted a photo of herself in full-on Day of the Dead makeup. If this is what she wears before Halloween, we can't wait to see what costume she chooses tonight!
