While the two have been known to wear matching outfits, the Keeping Up With the Kardashian stars took things to another level with their latest twinning moment.
Taking to Instagram, the KKW Beauty founder celebrated her famous family in honor of National Sister Day. "Not sure what I would do without them," she shared online, alongside several images that she's taken with her siblings, Khloe Kardashian, Kourtney Kardashian, Kendall Jenner and Kylie.
Naturally, Kim's first pic caught the attention of her 145 million Insta followers, as she and the Kylie Cosmetics founder sizzled in matching bodysuits that were reminiscent of Florence Griffith Joyner's famous tracksuits.
While the 38-year-old reality TV personality opted for a cream colored ensemble, her baby sister donned a vibrant lavender suit. The two also rocked colorful makeup lewks that made their outfits pop even more.
Along with their fiery 'fits, the pair showed off their upcoming KKW Fragrance collaboration.
