Kourtney and Kylie arrived at Coachella just one day after the birth of their niece by sister Khloe Kardashian.
The two sisters were photographed together in Indio, California, ahead of a full weekend of musical acts including Beyonce, Cardi B and The Weeknd, reports people.com.
Kourtney, 38, looked ready for the sun's rays in a black see-through tank top with a black bra, black shades and dark gray Adidas sweatpants.
In a second photo, Kylie wrote, "cotton candy cream kylighter ."
The new mother also got busy showing off her recently toned body, just two months after giving birth to daughter Stormi. She shared a profile view of her post-pregnancy body on Snapchat wearing a black bra and jeans.
Kourtney also posted a photo of herself in a swimsuit by Fashion Nova, featuring a red top and black bottoms.
"Reckless @FashionNova #ad (sic)," she wrote in the caption.
