Kendall, Kylie 'Keeping up with...' Kim Kardashian?

Kendall Jenner and Kylie Jenner are busy promoting their latest fashion venture at a mall in Glendale, California.

Kendall, 18, wowed in a black lace long-sleeved For Love & Lemons top, and she teamed the look with a black tulip skirt which showed off her long legs.

16-year-old Kylie looked sleek and sophisticated in a strapless blue top with a V-shaped neckline and peplum detail, which she paired with matching shorts.
