Kendall opted for a 'Kalifornia' white muscle tank with a black Zara skort (that has been seen on everrrrrrybody this summer). You can grab her $25 tank here and mini skort here.
Kylie looked super cute in her faux leather skirt overalls and a cropped tribal print top (both from their PacSun line). She topped her look off with a pair of Christian Louboutin 'Azimut' sandals. You can cop her look here, here and here.
I really love that Kendall and Kylie created a cute, age-appropriate and AFFORDABLE line for girls and actually wear it themselves.
