Kourtney Kardashian flaunts her chest in a very risqué low-cut dress holding her son in her arms

The reality star revealed her complete Christmas look while she attended the lavish bash thrown by her sister, Kim Kardashian.

Kourtney Kardashian took to Instagram to share several photographs of her and her son, Reign, as they posed for the camera during the party.

Kourtney stunned in a glamorous, low-cut black gown that featured a wide sash. The revealing ensemble flaunted her toned body and showed off her lean legs.

She fashioned her hair slicked back and pulled it into a high top knot. Choosing to add just a slight dab of makeup, Kourtney completed her fashion-forward look with black and beige pointy heels.

In one of the photographs, the 39-year-old star was even spotted holding sister Khloe’s baby, True, while Reign stood at her side.

Meanwhile, Daily Mail reported that Kourtney’s mother, Kris Jenner, spent over $500,000 for the lavish party that was held at Kim and Kanye West’s mansion.

The official planner of the party event, Mindy Weiss, also took to Instagram and expressed her delight at how all the arrangements looked.

The celebrity planner wrote on her post, “It was a whoville magical white Christmas last night. Thank you.”

Weiss, who was hired by Jenner, has also collaborated with other A-list celebrities including Ellen DeGeneres, Jessica Simpson, and Serena Williams.

Weiss started her work on the lavish winter-themed Christmas party several months ago, as per a Daily Mail source. The idea of creating a ‘white winter wonderland’ was provided to her by Jenner.

The source further revealed that the instructions provided to Weiss were to create a ‘dreamy look with no red and green.’ Moreover, Kim’s husband, Kanye West, has specially demanded the event to be ‘over the top for his three kids.’

The annual Kardashian-Jenner Christmas party is usually thrown at Jenner’s Calabasas home. However, this year, the spectacular Christmas Eve bash was hosted by Kim and West at their own home.

Kim previously also took to social media to share some of the videos from the party while she bonded with several of her guests.
