A favorite of the Italians - she's currently starring in campaigns for Gucci, Versace, and Fendi - Abbey Lee Kershaw not only models, but also sings in her own band Our Mountain and continues to inspire Polyvore users with her personal style, returning to the site's ranking in sixth place this week.

Her signature looks owe their undeniable stylishness to long, flowy maxi dresses, combined with leather jackets or leopard-print coats, as well as unexpected color mixes or layerings, almost all of which make for perfect transitional looks in between summer and fall.

Meanwhile, TV reality star Kim Kardashian is getting a boost thanks to her and her sisters' collection for US retailer Sears that is being promoted prior to its August 11 launch.
