This weekend, celebrities took to the street and embraced the cool weather. We saw Olivia Wilde sporting a casual look while walking her dog in New York City and saw Heidi Klum rooting on her son at his football game in striped black and white cropped pants and a chic fanny pack in LA.

Back in New York, the stars were out to support the American Foundation for AIDS Research's (amfAR) annual benefit gala. Kate Hudson stole the show in a full length red gown with a plunging neckline and gorgeous envelope clutch.

Which is your favorite look?
