They're off!

After a wedding brunch at Valentino's Chateau de Wideville, Kim Kardashian and Kanye West are heading to the Palace of Versailles, once home to Marie Antoinette, for a private tour and dinner with their 120 guests.

The bride and groom left their Paris apartment in a coordinating neutral palette. West wore a sand-colored suit with no shirt while Kardashian, 33, looked stunning in a sexy white Maison Martin Margiela dress with winged sleeves. The tuxedo jacket-inspired look featured a cut-out on the front, showing off her cleavage, and a high side-slit on the skirt. Her hair, styled by Jennifer Aniston's hair pro Chris McMillan, was swept back into a braided chignon with height in the front.

Kardashian's sisters, Kourtney and Khloe Kardsahian, Kylie and Kendall Jenner, and mom Kris also have adopted the seemingly monochromatic dress code for the weekend. Khloe, 29, opted for a long nude sequined gown, while model Kendall, 18, contrasted the group in a navy satin dress.

Escorted by her love Scott Disick, eldest sister Kourtney, 35, wore a white pant suit with a ruffled jacket, and momager Kris, 58, also chose a short white dress with long sleeves. 

The group made a quick change after their earlier brunch hosted by Valentino. The ladies arrived back at the George V Hotel around 3:30 p.m. BST to change into their evening attire. "They're all in a hurry to change real quick right now," another source told Us Weekly. At around 6 p.m., they all met in the lobby before leaving for Versailles.
