The TV personality, who welcomed her daughter Stormi with rapper beau Travis Scott in February, donned a pair of silver strappy heels, finished off with elaborate feathered wings.
Kylie caught the eye with her typically glamorous make-up choice, complete with sultry false lashes, heavy strokes of bronzer and peach lipstick.
Fitness fanatic Khloe, who shares six-month-old True with boyfriend Tristan Thompson, flaunted her impressive abs in a sheer lace VS balconette bra.
She paired the look with see-through heels, and a dramatic shawl that served as her statement accessory.
It also isn't Khloe's only look this Halloween as she shared sweet snaps with baby True.
Kim, 38, maintained her vixen persona in a similar lingerie set to sister Khloe.
The petite star also wore trendy Yeezy clear stilettos and angelic angel wings.
Kanye West's wife lived up to her trademark look as she styled her raven locks into glossy curls and opted for full-on glamorous make-up, which featured bronze eyeshadow, fluttery false lashes and nude lipgloss.
She later revealed that their ensembles were official outfits given to Victoria's Secret models, taking to Instagram to share a snap of the sisters that she captioned: "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."
The mother-of-three has been boasting about dropping more than 20lbs after weighing about 140 for the longest time.
And as a result, she has been giving her 116 million Instagram followers more of a glimpse into her workouts — posting near daily updates of her time in her private gym.
Kourtney, 39, stunned as she displayed a hint of her gym-honed abs in the full lingerie set, while showing off her lilac pedicure in perspex heels.
Setting herself apart from the pack, the star, who was once branded "the least interesting sister to look at" by sister Kim, completed her look with wings embellished with sequins and pearls.
Kourtney swept her wavy tresses into a half up half down style with a side fringe to reveal her glowing complexion, complemented with sparkling make-up in a neutral-toned hue.
Supermodel Kendall, 22, who is returning to the VS stage this year, sustained her catwalk queen status in a VS lace bra and a sheer bodice.
The Vogue star appeared to make the car park her runway as she finished off her sizzling look with over-the-top feathered wings.
Kendall's display comes after she was confirmed for this year's Victoria's Secret Fashion Show, alongside fellow model Gigi Hadid, last week.
Brian Atwood — the man responsible for the shoes the 2018 models will be wearing — let slip on social media that the two beautiful models will be part of the spectacular lingerie catwalk show which will be taking place in New York City this year.
Kendall missed the event last year due to a contractual conflict, as the Keeping Up With The Kardashians' star was the face of La Perla lingerie and unable to model for any other lingerie brands.
This year's catwalk show will see the brand return to New York City, after hosting the event abroad for the past few years.
However, while the show is taking place in the Big Apple, Victoria's Secret is bringing some British flair to the mix, announcing earlier this month that it will be collaborating with London-based designer Mary Katrantzou on a capsule collection that will make its debut on the runway.
