Adanola

Kendall Jenner posted on IG in the khaki Adanola Ultimate Leggings last month, and already the fall-ready finish has become a fashion insider favorite. The deep khaki isn't the only non-black shade to rise in popularity this fall; celebs are also backing beige, chocolate brown, and heather grey. Follow Kendall's lead and pick up a pair of the best-selling leggings to experience the buttery-soft fabric.
