Let's just check that off the list. Elsa & Anna, sisters. Kylie & Kendall, sisters. You get it!

Every girl in the world wanted an Elsa braid. Teens (and adults) everywhere emulate the stylings of Kylie and Kendall.

In their new PacSun promo, Kylie and Kendall brave the snow just like Elsa and Anna

For Elsa and Anna, it was a ball. For the Jenners it's... every weekend.

Speaking of hair, Kendall's crystal-blue dye job reminds us of Elsa's winter castle.

Just like Elsa and Anna know how to prepare for a ball, Hollywood's most stylish sisters know how to dress it up.

Just like Anna loves Sven, Kylie and Kendall love their furry friends.

The Kardashians are something of a Hollywood royal family.

Though Anna's adventure may have been more honorable, Kylie and Kendall do their fair share of jet setting.

Kylie is reportedly dating rapper Tyga and there are rumors of marriage--and the baby carriage.

Elsa and Anna love to sing, and Kendall and Kylie love music, too! More specifically, they love musicians. Kendall has dated Harry Styles while Kylie is currently dating Tyga.

Above all, Elsa and Anna were always there for each other. Kylie and Kendall are no different.
