Kourtney Kardashian Wore A Kendall Jenner T-Shirt—Talk About Sisterly Love!

Love them or hate them, you can't deny that the Kardashians are insanely close—remember when Khloé let Kourtney give her a bikini wax before seeing ex-hubby Lamar? I don't think you can get much closer than that. And now, Kourtney Kardashian was seen wearing a t-shirt with Kendall on it. That's some serious sisterly support.

Kourtney was snapped wearing her sister on herself while out in L.A., picking up her kids from dance class, according to People. She rocked the loose fitting white tee with a black and white photo of Kendall riding a horse on it with casual, light-wash ripped jeans, oversized sunnies, black booties, and a Mansur Gavriel backpack hybrid. And of course, the iconic Cartier Love bracelets. Très California chic.

Kylie also has her own version, with a black and white close-up of her face and signature badass nails. While they aren't available online, the rest of their collections is available on the PacSun website.

Kourtney's Instagram post, which she captioned "Peep my shirt. #kendallandkylie #pacsun" promoted her two youngest sisters' most recent "festival collection" for Pac Sun, which includes bohemian-meets-bad girl pieces, like white lace bell bottoms, cut-out rompers, and fringe shorts. And even a stylish hat to block those harsh rays.

And since festival season is coming up, here are 5 pieces from their collection that would be perfect for dancing the day (and night) away.

1. The Fringe Skirt, $39.95

2. Short Sleeve Off the Shoulder Romper, $44.95
