It doesn’t get any more sisterly than this! Kim Kardashian and her little sis Kylie Jenner stepped out in matching outfits in Calabasas, CA on Monday, June 11 — and fans are mistaking them for twins! While the reality stars do look alike on a daily basis, there was something about the gray, monochromatic, skintight leggings that made it difficult to tell them apart.

And that wasn’t all. The two matched in their spandex outfits all the way down to their Yeezy sock boots and chic accessories: huge sunglasses and a Starbucks cup of iced coffee. The entire look from both girls is rumored to be from Kanye West’s unreleased Season 7 line, and honestly, what great advertising for the rapper.

Even though Kim, 37, and Kylie, 20, are nearly 20 years apart, the sisters have always donned similar styles in both fashion and beauty. “The people who really inspire my style-wise are obviously Kim and Kanye,” Kylie told People of her style icons back in 2015.

And since Kylie welcomed her baby girl, Stormi Webster, with boyfriend Travis Scott on Feb. 1, Kylie’s entire family, including Kim, has stepped up to help her adjust to new motherhood. “Everyone in the family is doing their part to help out in their own ways. Everyone wants to be super involved, so each person is doing whatever they can,” an insider previously told Us Weekly.

“Kim, Kourtney, and Kris are particularly engaged as they have been moms for a while now and are helping Kylie walk through being a mom for the first time. They’re helping her change diapers, giving her day-to-day mommy advice and just being there for Kylie when she needs a shoulder,” the source continued. “Kylie is so appreciative of their support and could not have done this without them.” So sweet!
