The Sin City actress looked cool, casual and ever-so-stylish as she took a stroll in Los Angeles yesterday (3 October).
Jess rocked a fierce pair of distressed boyfriend jeans, rolled up at the ankle. She gave her slouchy denim a feminine twist with a pretty floral top, adding a smart blazer and oversized sunnies.
We reckon boyfriend jeans work best with statement heels, but comfy black ankle boots like Jess' are a great daytime alternative.
She wore her newly-cut tresses in a side parting, adding barely-there make-up and chic navy talons.
And she carried what can only be described as a total necessity - a giant flask of coffee.
Well, with two kids, her own company and swanky events to attend, she's got to keep her energy up somehow!
