The spooky season of Halloween has knocked on our door for the trick-or-treat and all eyes are on the celebrities. Just like every year, the Kardashian family has been storming the internet with their spooky yet sizzling costumes. And among all the renowned Keeping Up with Kardashian celebs, Kylie Jenner has been standing out with her Halloween 2021 costume. The American actress model and fashion mogul who is soon going to welcome her second baby with beau Travis Scott slipped in one of her most glamorous and tempting attires for Halloween 2021. Amid her second pregnancy, Kylie Jenner took to her Instagram to give a sneak-peak of her Halloween costume with her little mermaid Stormi.

The fashion and model mogul has completely changed the curve of the fashion industry with her sartorial choices.

Kylie Jenner kept her Halloween costume low-key this year—by Kardashian-Jenner standards, anyway, amid her second pregnancy.

Showing off her ever-growing baby bump, the makeup mogul donned a sleek, long-sleeved black catsuit and matching black cat ears, while her other half opted for a Michael Myers face mask.

As for their 3-year-old, Stormi seas-ed the day by dressing up as a mermaid, which included her rocking a cute shell-and-pearl tiara and white seaside-themed purse as accessories.

The 24-year-old star who already shares 3-year-old daughter Stormi Webster with ex Travis is expecting her second child with the rapper.

The Keeping Up with The Kardashians star shared a few sweet pics of her family in celebration mode to Instagram, captioning the Oct. 31 post, "In full mommy mode this Halloween. I hope everyone has a safe night."

Sister Kourtney Kardashian, who is, of course, mom to three little ones of her own, couldn't agree more with Kylie's sentiment, commenting, "Full mommy mode is my favorite! Hold onto it!"
