So it's no surprise that the chic E! star stepped out on Friday, Jan. 24 in Los Angeles in one of her trademark signature styles.
The 33-year-old showed off her enviable curves in a black see-through mesh long-sleeve top and a matching above-the-knee fitted skirt. Kim completed the look with natural makeup, nude strappy heels and wore her sleek hair down with a side part.
"BFFs!" was the simple caption accompanying the pic of the two precious girls.
Kim and Kanye West's 7-month-old baby girl and Scott Disick and Kourtney Kardashian's 18-month-old little one are all about family time. And of course, they adore 4-year-old Mason, who has seniority amongst the cousins.
"Its so cute how they all love each other so much!" Kim, 33, gushed in a Mobio Insider Q&A last month. "Penelope & North are bff! Mason bosses them around and is super protective."
