Khloe Kardashian sizzled up a storm on Thursday as she arrived at her sister Kylie Jenner‘s canned vodka soda brand Sprinter launch party in West Hollywood.

The reality star, 39 — who was the only Kardashian/Jenner sibling that showed up to support Kylie at the event — had all eyes on her as she went braless in a daring sheer black mini dress for the soirée, held at Catch Steak.

The sultry ensemble clung to her famous curves and highlighted her ample cleavage. It featured one off-shoulder strap and a short sleeve on the other arm.

The mom-of-two completed her look with a pair of black heels, large black sunglasses, and a bright blue handbag.

Her waist-long blonde tresses cascaded down her shoulders and were lightly curled into beach waves for the occasion.

It was revealed earlier this month that Kylie would be entering the alcoholic beverage market with Sprinter.

Kylie’s older sister Kendall, 28, already has a tequila line named 818 which debuted in 2021 and has been doing well; there was even a special made for the brand in the shape of an 8.

Sprinter is a 100-calorie canned vodka soda made with premium vodka, sparkling water and fruit juice. It is available in four flavors: Black Cherry, Peach, Grapefruit and Lime.

The alcoholic sodas are scheduled to hit stores March 21. Sprinter will be sold in an 8-can variety pack for $19.99. It is 4.5% ABV.

Kylie recently issued a statement where she expressed via USA Today why she chose to embark on her newest entrepreneurial project.

‘Sprinter is my answer to the growing consumer demand for quality canned cocktails,’ she said.

Kylie went on to speak about how she wanted to her new line of products to appeal to younger consumers.

‘Not only does Sprinter have a unique bold branding that captures the feeling of fun with your friends, it is also the best tasting vodka soda I’ve ever tried – and I’ve tried a lot,’ she said.

Beverage development expert Chandra Richter, who collaborated with Kylie while developing Sprinter, also spoke about the painstaking process that went into coming up with each offered flavor.

‘We held numerous tastings over the past year to ensure each of our four flavors are as natural and true-to-fruit as possible,’ she said.

Kylie’s mom Kris was the first Kardashian-Jenner family member to arrive at Thursday night’s big launch party in West Hollywood.

The sighting comes just days after her younger sister Karen Houghton ‘unexpectedly’ died at the age of 65 on Monday.

Kris put on a brave face in order to support Kylie’s latest business venture. She looked stylish in a white tuxedo with 70s-inspired black lapels and a ruffled black button-up shirt.

She was accompanied by her longtime boyfriend Corey Gamble, who recently enjoyed a ski trip in Aspen with none other than Prince Harry.

Kylie’s BFF Anastasia ‘Stassie’ Karanikolaou was also present, and looked like sheer perfection in a see-through black dress.
