Kylie Jenner & Kourtney Kardashian Get Their Shop On!

Kylie Jenner and her good pal Pia Mia stop by Barney’s New York to do some shopping on Sunday (August 23) in Beverly Hills, Calif.

That same day, the 18-year-old reality star’s older half-sister Kourtney Kardashian was seen out with her kids Mason and Penelope (not pictured) at Chuck E. Cheese’s in Los Angeles. Later in the day, Kourtney went shopping at a local mall.

Kylie and Kourtney just recently returned back from their vacation in St. Barts, where they were seen sunning themselves in bikinis!

FYI: Kylie is carrying an alice + olivia backpack. Kylie is also wearing Under Armour leggings.
