The sisters did a group costume in 2018 and KILLED it. 1
All five Kardashian-Jenner sisters dressed up as Victoria's Secret angels and they looked beyond perfect. "Thank you @VictoriasSecret for sending us actual runway looks and real wings to borrow for the night!!! OMG a dream come true! Got to be a Victoria Secret Angel for the night! And Kendall got good practice lol" Kim wrote.
Kylie gave the 'Little Mermaid' a sexy twist. 2
All the talk about the remake of the Little Mermaid must have inspired Kylie to dress up as the iconic Disney princess. Her fiery red wig was perfection and her costume looked incredible on her toned body. She captioned the pic: "Ariel grew up.. ♥️" She sure did!
Kim really nailed her 2019 Halloween costume. 3
Leave it to Kim to find a costume that perfectly describes her life at the moment. She dressed up as Elle Woods from Legally Blonde in 2019, the same year she revealed she was pursuing a law degree. Pretty clever, Kim!
Kylie might just be the queen of Halloween. 5
This pink butterfly look is beyond gorgeous. Those wings are beautiful and the best part is that her daughter, Stormi, had the same costume.
Kylie had to dress like a Playboy Bunny at least once in her life. 6
What's a better time to do it than on the same year that you appeared on the cover of Playboy magazine? She looked incredible and the corset on the costume made her waist look incredibly small.
Kylie won Halloween 2016. 7
Kylie's costume as Christina Aguilera in the "Dirrty" video was a fan favorite. A video of her dancing along to the song while in costume became the most watched of the year, and Xtina totally loved it.
Kim just loves dressing up like Cher. 8
Cher seems to be Kim's go-to inspiration. Since they both come from Armenian roots, Kim loves dressing up as the singer, and she nails it every time.
Kim and Kourtney dressed up as the iconic Michael Jackson and Madonna. 9
Kim and her big sister, Kourtney, dressed up as Michael Jackson and Madonna when the musicians attended the Oscars in 1991 together. This is perfect!
Kim also did the mermaid thing back in the day. 11
Kim skipped the Disney Ariel look and opted for a more realistic kind of mermaid. Her partner, Kanye, dressed up as a sailor that year, giving us major inspiration for a couples' costume.
Kylie really outdid herself with this one. 12
Kylie really took things to the next level with her Barbie costume in 2018. She looked so beautiful and so doll-like it was almost creepy because of how accurate it was.
Kourtney really nailed this look. 13
The Poosh founder dressed up as pop star Ariana Grande and absolutely got it right, down to the microphone and knee-high boots.
People were not happy with Kim's Selena costume. 14
Latinos in particular were not fond of Kim dressing as the Tejano queen. Some even called it cultural appropriation. All of that aside, Kim looked really good in the iconic plum one-piece outfit Selena wore for her last concert.
Khloé really made the most of her daughter's first Halloween. 15
Khloe and True made the prettiest little unicorns on Halloween 2018. Khloé and her little girl also dressed up as tigers, and True had plenty of other costumes that year. So cute!
Khloé showed off her best Halloween look in 2016. 16
Khloé went all out with the makeup and hair for her Storm costume. The eyes, the hair, everything looks so good!
Kylie loves dressing up with her friends. 18
She was a warrior princess while her friends were ninjas in 2015. She looked so good!
Kim and Kanye West used to dress up together. 19
The couple went as Batman and Catwoman to a Halloween party in 2012 and they looked so good. We hope they start dressing up together again!
Kourtney and Scott Disick also did couple costumes. 20
The former couple looked so cute in their Batman and Robin costumes in 2012. We love that Scott played the sidekick and that his ex-girlfriend was the superhero.
