Chicago’s younger brother Psalm, 5, donned a checked shirt and a leather waistcoat as he posed with his cousin Tatum, 2 (the son of Kim’s sister Khloé Kardashian), who sported a double denim look.
Kim herself rocked a mainly all-black leather look, complete with a cowboy hat, an unbuttoned shirt, a western belt, and blue jeans under a pair of chaps. She took a series of mirror selfies.
Among the photos was an eye-catching personalized cake for Chicago. It featured a pink and white cowboy boot, a western belt, and ‘Chi’ written out in pink rope.
“We are setting up for Chicago’s cowgirl-themed birthday party,” Kim said in one post. In the video, she panned the camera down a long table covered with a pink gingham cloth, cowboy boots, and vases filled with pink and white flowers. Hay bales for guests to sit on were also covered in pink gingham.
