Kylie Jenner sizzles in a sexy backless red gown at the launch party for her debut fragrance Cosmic in LA

Kylie Jenner showcased her jaw-dropping figure in a racy red gown to the launch party for her debut fragrance Cosmic in Los Angeles, California.

In images taken ahead of the event, uploaded to her Instagram account on Thursday, the reality star, 26, posed for a sexy shot as she glanced back over her shoulder in the hallway of her Holmby Hills mansion, where she resides with her kids Stormi, six, and Aire, two.

The makeup mogul oozed glamour while striking a series of playful poses with her back to the camera and wavy brunette locks pulled back into an elegant updo.

A second picture showed the mother-of-two serving a smoldering stare towards the camera as she made her way to the star-studded occasion, attended by TikTok star Alix Earle and influencers like Brittany Xavier.

‘Out of this world,’ she captioned the slideshow. ‘Looooved this glam last night celebrating the launch of COSMIC.’

Minutes later, she uploaded snaps from the bash as well as some full-body pictures of herself, which gave fans a glimpse of her entire outfit.

She accessorized her floor-sweeping dress with a pair of white platform heels.

Once inside, Jenner mingled with attendees and was seen sipping a glass of rosé.

The bar was stocked with her new canned vodka soda, Sprinter, and sister Kendall Jenner’s award-winning 818 Tequila.

The TV personality’s perfume, which has been described as a sweet and elevated scent, contains notes of star jasmine, blood orange, golden amber accord, red peony accord, vanilla musk accord and cedarwood.

Her comment section was full of messages praising her glamorous look.

‘The most gorgeous of the night,’ one fan commented.

Another wrote: ‘Kylie so beautiful and stunning.’

‘The red looks so good on you,’,’ a third wrote.

Earlier this month, Jenner told fans that the creation of Cosmic took years and ‘many many rounds to create the perfect signature scent.’

Her fragrance became available March 7, just months after launching her clothing brand, Khy.

Jenner has kept busy in recent months as she continues to keep fans on their toes with her elaborate rollouts.

‘Khy aims to redefine the modern wardrobe by offering edited collections that seamlessly blend luxury with everyday style, spanning a diverse range,’ the website for her fashion brand reads.

In July, reports began to surface that she was launching her own fast-fashion line with the help of Emma Grede.

Grede cofounded denim company Good American with Kylie’s sister, Khloé Kardashian, in 2016, and Kim Kardashian’s shapewear line, Skims, in 2019.

Jenner officially announced Khy in late October, with the first drop launching November 1.
