No Need to Phone a Friend; Jessica Alba Is Your Street Style Lifeline

The trendsetter lightened things up in a perforated top, canvas Jenni Kayne flats, a long blush blazer, and a coordinating Louis Vuitton bag.

Jessica nailed business-emphasis-on-casual in a rosette Michael Lauren jumpsuit, Sarah Flint pointed flats, and a go-with-everything chambray shirt while heading into The Honest Company's office in Santa Monica.

Jessica perfected ladylike glamour in a floral Topshop midi and crisp white accessories in NYC.

Isabel Marant for H&M joggers, throwback Doc Martens, and a cool-girl fedora rounded out Jessica's NYC travel style.

What's cooler than a chambray top? A chambray jumpsuit.

We love a matching set as much as the next girl, but this sleek Tanya Taylor combo was just too cool for words!

Donning chambray joggers, on-trend Birkenstocks, and uberchic accessories — a canvas fedora, round tortoise shades, and a pale pink Louis Vuitton tote — Jessica once again proved why she is our street style lifeline.

The trendsetter beat the Winter blues in a cozy cardigan, printed Tory Burch high-tops, and a navy Janessa Leone fedora.

Snowy essentials: a neutral toggle coat, dual-textured riding boots, and a fur-trimmed trapper.

Alba wrapped up her playdate style — a charcoal v-neck and cuffed army-green pants — with tribal driving loafers and red shades.

Alba took in all that Paris Fashion Week had to offer, posing in a graphic-print long-sleeved dress and sunny wool coat, both by Kenzo, and stacked lace-up Rupert Sanderson x Antonio Berardi booties.

Alba's statement Simone Camille backpack made her cashmere Inhabit cardigan and dark blue denim anything but boring.

Alba brought retro vibes to Paris, styling a striped pastel Chloé coat with
cat-eye shades and a perforated Chloé tote.

Cropped denim, a dual-texture Sandro jacket, and trusty Jenni Kayne flats made up Alba's LA office look.

Jessica's earthy separates — printed Wayf track pants, a dark green Current/Elliott button-down cinched around her waist, and metallic Converse — are ideal for a family park day.

Alba gave her travel style a Parisian-chic nod with a striped "Je T'aime" Talbots sweater while catching a flight to the City of Light. D'Orsay flats and a crimson Saint Laurent tote completed her casual-cool ensemble.

What toes the sweet yet statement-making line perfectly? Jess's snake-print Diane von Furstenberg skirt.

The style star layered up in a plaid shirt, navy lurex coat, and luxe leather pants. She accessorized her rainy-day ensemble with patent leather ankle boots and a python Nina Ricci bag.

Jessica's LA look was all about the accessories: mirrored Westward Leaning shades, Charlotte Olympia x Tom Binns kitten flats, and a sassy A.L.C satchel.

Proving the power of a (snowy) statement shoe at the Christian Dior during Paris Fashion Week.

While strolling around LA with husband Cash Warren, Jessica suited up in a military-meets-varsity Pam & Gela jacket and cutout sandals. We're kind of loving her half-metallic shades, too.

Alba's preppy personalized handbag offset the rocker vibe of her Mick Jagger Transmission tee and leather leggings.

Styling her company's tee with cobalt chinos and white leather Yosi Samra flats in LA.

Alba toughened up her gauzy mini with a chunky leather jacket and black ankle boots in Berlin.

If this isn't the coolest park-day style, we don't know what is.

Jessica married black and blue via a cobalt blouse, studded Isabel Marant boots, and a supple Zadig & Voltaire satchel.
