Sure, Kendall Jenner is turning 18 on Sunday, and Kylie Jenner now has her driver's license...but they're not too old to celebrate Halloween!
The youngest sisters of the Kardashian-Jenner clan got in the holiday spirit yesterday, and showed off their costumes today on Instagram.
Kendall was the first to share, and the young model went with a cute costume that had a little edge: She tweeted out a pic of her cat outfit, complete with the appropriate emojis.
At first look it's all cute and innocent, but check out the fangs!
As for Kylie, she chose a costume that is not only a childhood classic, but would also fit in with the dark color palette of her recent personal style.
"Channeling my inner Wednesday Addams yesterday," Kylie wrote with a moody black & white pic of her in a black coat with her hair in braids.
Nailed it!
There was one more member of the family whose costume Kendall just had to show off on Instagram...her new puppy, Blu!
The grey pup got a matching pair of grey mouse ears to wear. "She loves her Halloween costume," Kendall wrote with a pic of Blu looking less than amused.
Judging by that face, we wouldn't say she "loves" it. But she's definitely adorable!
Blu was an early birthday present to Kendall from big bro Rob Kardashian, and Kendall has been shutter-happy ever since, posting plenty of photos of the pup on Instagram.
Kendall's birthday celebrations continued earlier this week, as the Kardashian-Jenner family took a trip to Six Flags Magic Mountain as an early birthday party for Kendall, who turns 18 on Sunday.
In fact, Kim Kardashian posted some pretty entertaining videos of herself and her siblings riding roller coasters at the park!
