Jessica Alba did just that when she hit up Comic-Con in support of Sin City: A Dame To Kill For. Though her off-duty style has been gorgeous eco-conscious mommy lately, Alba had no trouble amping up the fierceness with a sexy side-braided 'do. Don't pretend this isn't going on your Pinterest.
The 32-year-old actress was a fashion favorite in her printed Zimmermann skirt and black Tanya Taylor bra-style top, but it was her sideswept hairstyle that hinted at a darker, edgier mood. Anyone else getting an Alice Dellal vibe from the former Dark Angel star?
Of course, the mother of two didn't go the whole undercut route à la Dellal and Natalie Dormer. Still, the extreme part, serpentine braid, and spiky Maria Black earrings are pure badass material. Once a femme fatale, always a femme fatale.
