Preparing for a long and demanding day, Jessica Alba dropped into a Beverly Hills coffee shop for a caffeine boost yesterday (July 1).

The always-stylish “Good Luck Chuck” cutie donned a purple maxi dress with a black cardigan and black booties as she scurried back to her car, drink in hand.

Jessica recently talked about her own summer style with InStyle magazine- “It’s appropriate, but playful. I like to wear whatever fits my mood. Sometimes I’m really feeling ’90s grunge, and I’ll wear my Doc Martens every day for a week, and that’s a certain look you’re going for. You have to commit to the Docs, and everything builds from there!”

As for how she assembles an ensemble, Alba noted, “Usually my outfits do sort of revolve around the shoe. Then sometimes I feel like doing casual dress pants and a T-shirt and a blazer, and trying to be business-y. It’s all over the place, but it’s for sure appropriate for what’s happening. If I’m going to the office, it’s more appropriate for that environment, versus if I’m going to a tech conference or a press conference or hanging out on the weekend with the kids. It’s usually functional for that occasion.”

And Jessica certainly has some summer staples. “I am for sure wearing Birkenstocks again. They are so comfortable. I’m not sure what to say about it. I’m not sure if it’s a good choice. Some of my friends think it’s the worst thing on the planet. And some of my other friends are down, so I’m not sure. I am committing to it, so that’s happening. And those Ancient Greek Sandals—I have a few pair of those, and I am for sure wearing those. And I have these white Vans. This trip, I built my entire going-to-the-airport outfits around my white Vans. I really do. If the two things, my bag and my shoes are white, then everything else can be colorful. It can be a mess as long as the bag and the shoes are white. There’s no better airport shoe as far as comfort goes.”
