The Flinstones
Meet the Wests! Kim's whole clan got in on the Flinstones fun -- and, yes, that is Kanye in the dino suit! "This family pic was such a challenge because Chicago was so scared of Dino! LOL We tried to explain and show her that it was just daddy but she didn’t get the concept yet! So shout out to the photographer for editing her in & making our family Flinstones dreams come true!" the mom of four explained on Instagram.

Kourtney kind of has a thing for dressing up as the hottest ladies in music, and 2019 was no exception when she sparkled and shined as Spacey Kacey.
Superheroes

'101 Dalmatians'
Khloe struck a pose as Cruella De Vil with her Dalmatian, daughter True.
Golden Goddess
We're actually not sure what exactly Kendall dressed up as for her Halloween birthday bash, but she looked like a golden warrior princess doing it!

For Kendall's birthday party, one of Kylie's many 2019 costumes was a glittery fairy. She paired her itty bitty periwinkle fringe costume with a bleach blonde wig and pointy ears. "Last night was magical ??♀️," she wrote on Instagram.

Diamonds are this girl's best friend! Kylie transformed into the Hollywood icon for V Magazine.

The Keeping Up With the Kardashians star and her BFF, Stassie Karanikolaou, hopped into their second outfits of the Halloween 2019 season: Playboy bunnies.

And Kendall got good practice lol," Kim wrote on Instagram.

We had to do a double take after Kourtney shared her spot-on interpretation of the pop star, which she naturally captioned, "God is a woman," aka the title of one of Grande's most recent singles.

Kim embraced her inner Selena via a sparkly purple cutout jumpsuit. “My fave Selena!!!!” the Keeping Up With the Kardashians star captioned a video of herself twirling around in the sexy look.
Christina Aguilera
Could there be two Xtinas? Kylie looked like a dead ringer as she channeled an infamous look from Aguilera's "Dirrrty" era for Halloween 2016.
