BACK TO SLIDE
Jessica Alba is never afraid of a trend, which is probably why she looks so good when she sports one -- confidence is key, after all. The actress, mom, and Honest Company founder showed up at Comic-Con in San Diego this week, for the West Coast leg of her Sin City: Dame to Kill For press tour. Dressed in a Tanya Taylor cropped top and Zimmermann midi skirt, Jessica showed off an enviable tan, and an even cooler hairstyle.
Joined by decidedly edgier co-star Rosario Dawson, who rocks a Skrillex-style half-shave look, Jess sported a complementary hair look. It looks like a deep side part from the front, but there's an awesome braid running down the right side of Jessica's head. It's a cute, playful look for summer -- no head shaving necessary! As for everyone else who showed up to Comic-Con...well, we'll let you decide on that one!
