From locales around the globe, a group of today's most stylish stars put forth their end-of-summer best. January Jones and Kate Bosworth held onto the season with vintage-inspired and vibrantly hued dresses, respectively. Sienna Miller and Lais Riberio seemed to be looking towards fall with moodier color palettes and ankle-grazing trousers. Lily Collins fell somewhere in between the two groups, marrying a heat-beating two-piece with autumn's most arguably beloved footwear: knee-high boots.
