Jessica Alba: March's most fashionable Actress Jessica Alba has spent the month jet-stetting around the globe, giving a masterclass in how to dress effortlessly for every eventuality along the way. As a California girl through and through, we could forgive Jessica Alba the sin of turning up at frosty Paris Fashion Week in a puffa jacket - just about. But there's no climate the honey-skinned actress can't dress to perfection for, and she's spent the past month proving as much. Partaking in Paris Fashion Week's headline acts with a front row seat at Stella McCartney, Kenzo and Valentino, the Sin City star also found herself in demand at Carine Roitfeld's stylish soiree to launch her second issue of C.R Fashion Book. Naturally, a cute, black Valentino frock adored with large bows was at her disposal.

READ: She Wears It Well - Jessica Alba With only a couple of days to re-organise her closet, Alba was whisked off to New York City to promote her book, The Honest Life, a tome about making healthy living "fun, real and stylish." Her designer friend Jenni Kane provided punchy florals for trouser-loving Alba to go with her leather-sleeved Michael Kors jacket, while she looked to Narciso Rodriguez for a teal, keyhole-cut dress for an appearance on Good Morning America. Several photocalls later, and we now firmly know that Jessica loves the power of a bold jacket or pair of statement trousers worn with a dainty heel.

Exhausted? Not as much as Alba's laundry helper must be this Easter. Take a look at her tirelessly fashionable month here...
