Alessandra Ambrosio looked cozy and chic in her Ellie Mae 'Celine' nubby knit cardigan ($380, elliemaestudios.com) paired with crop jeans, white sneakers and Louis Vuitton bag. The perfect fall look for traveling, class or running errands.

It's October and that means the leaves are falling, the pumpkin spice is flowing and it's time to reach for those warm, fall hues that make everything a bit cozier.
