Kylie Jenner slips into black jumpsuit as her sisters and mother join her for Kylie Cosmetics launch

Kylie Jenner stepped into a chic vinyl ensemble as she made her way to the launch of her new Kyle Cosmetics line on Tuesday evening.

The 24-year-old cosmetics mogul showed off her baggy black jumpsuit in her Instagram Stories as she prepared to the event.

She was set to debut the new Kendall by Kylie Cosmetics line, inspired by her older sister Kendall Jenner, who also attended the launch with her sister Khloe Kardashian and mother Kris Jenner.

Kylie posed in front of a mirror to share her striking look before the launch.

The jumpsuit featured baggy, rumpled legs and silver buttons over her midriff, culminating in an open olive-colored collar. 

The outfit featured a thick black belt around her midriff that dangled down to her knees, and patches of vinyl were worn away to reveal the tan fabric underneath.

She elevated her 5ft6in stature with a pair of pointy black heels. 

The Keeping Up With The Kardashians star had her raven locks tied back tightly in a ponytail, which showed off her chunky silver earrings.

‘My best friend!’ she cooed in another clip as she zoomed in on her pal Stassie Karanikolaou, who looked glamorous in a figure-hugging white top with a single long sleeve and a matching skirt.

The top was tucked into her skirt so as to leave to crescent-shaped cutouts over her hips, and she accessorized with a slim cream-colored handbag tucked under her arm that perfectly matched the ensemble.

Stassie’s makeup was also on point, and she wore her lustrous brunette locks cascading down her back and shoulder, revealing her modest silver hoop earrings.

Kylie appeared to be driving herself to the launch, and she snapped a photo of her sporty driving gloves on the steering wheel of her Lamborghini.

Although Kylie’s sister were more muted in what they posted ahead of the event, her mother Kris Jenner was happy to show off her preparations.

She sported an uncharacteristic bob, as the momager has favored a pixie cut in recent years.

Kris showed off her age-defying face with the new haircut in a short clip posted to her Instagram Stories as she got all made up for the big night.

Also joining her family members at the launch was Khloé Kardashian, though she just shared videos and photos of the event’s lovely decorations.

Tables at the celebration were decorated with gorgeous pale purple flowers and candles.

Naturally, Kendall’s 818 Tequila was served for guests, who could choose from two special cocktails: the Kylie — which featured the blanco tequila with grapefruit — and the Kenny — which used the anejo tequila mixed with an orange peel and a cinnamon stick.

Although she was one of the guests of honor, Kendall kept her launch outfit under wraps.

Instead, she posted a photo of her makeup palette — which featured cheeky shade names including ‘The Kendall to my Kylie’ and ‘Not not drinking’ — as she got ready.

Once she was at the launch event, the catwalk star snapped a photo of her dinner plate, which had been draped with a publicity photo of her and Kylie wearing purple floral headdress that matched the flowers at the celebration.

‘Our collections out tomorrow!’ she gushed in her text.

Kylie shared some more views of the lovely array, while showing her table placement next to Kendall’s.

The long dining table appeared to have rows of flowers running from end to end. 

Another cute clip showed Stassie and her puckering up dramatically for the camera.

Later in the evening, Kylie shared a short video of part of her mother’s toast.

‘I couldn’t be prouder than anyone in my entire life,’ Kris said to her two youngest daughters, which elicited a loving ‘aww’ from Kylie.

‘I love you @krisjenner [heart],’ she wrote over the video.
