The 15-year-old revealed in a new interview with Elle that she admires Kourtney's taste for unique finds, but still enjoys shopping sprees with Kim on occasion.
"I love Kourtney's style. Kim's more fun to go shopping with because she can take you to the huge stores and get you fun stuff, but Kourtney's better at finding cool things like vintage and putting them together," Jenner explained.
Jenner recently made her New York Fashion Week debut in the Sherri Hill runway show, while sister Kylie walked the catwalk in Avril Lavigne's Abbey Dawn exhibition.
Last month, Jenner hit back at critics, insisting that she is not too young to model and is considered old enough in the industry.
Kim Kardashian supported Jenner, calling controversy surrounding the teen's modelling career "ridiculous".
