Why we love it: The motorcycle jacket has been sending out the sexy-tough vibe ever since it landed on James Dean. It's not different in the 21st century, when ladies everywhere routinely count on one to add an edge to casual weekend outfits and ball gowns alike.
How to wear it: Style this piece as you would a blazer or cardigan — with anything. It's a cinch with whatever you already own, whether skinny jeans or a formfitting sheath.
Runway: Altuzarra, 3.1 Phillip Lim, and Saint Laurent
