Jessica Alba never seems to have an off day.
The actress-turned-entrepreneur was cheerful and businesslike as she dashed to her company's office in Santa Monica, California on Thursday.
Although temperatures were close to 80 degrees Fahrenheit that day, Jessica, 32, didn't seem to break a sweat as she sauntered from car park to entrance.
She's got style: Jessica Alba was chic in black jacket, graphic T-shirt and black leggings as she headed to her office in Santa Monica, California on Thursday
Although her ensemble was mostly heat-attracting black, her jacket was actually made of a synthetic and surprisingly light material that was perfectly tailored to her slender figure.
Jessica added comfortable black leggings, flat-heeled metal-studded ankle boots and a long loose T-shirt.
The mother-of-two also looked like she was heading to a photo session with her straight-styled locks.

Jessica's honey-highlighted brown hair was parted in the center and fell way past her shoulders.
Wisely she brought a large water bottle to stay hydrated in the summer heat and by the looks of it Jessica had already had a few swigs.
In addition to being a hard-working actress and mother to daughters Honor, five, and Haven, two, Jessica runs an eco-friendly home and baby brand called The Honest Company.
