Gwyneth Paltrow arrived at LAX to catch a flight in her signature casual-meets-cool travel outfit. And while we can't deny the classic appeal of her gray tee, faded jeans, and gray booties, we couldn't help but zoom in on two noticeably new additions to her jet-set getup: her black-and-white bags from Alice + Olivia's Spring 2013 collection and her bird tattoo. OK, so technically that's three new things to take note of. Neither Gwyneth's satchel nor tote is available to shop yet, but we don't — and shouldn't! — have to wait to get in on the sleek dual-tone look. What we love most about black-and-white bags is that, besides the fact that black and white are the hottest color couple right now, they feature two neutral hues that will go with just about anything in your closet. Plus, they're the easiest way to add instant sophistication to any piece, especially with your go-to denim. Thus, taking a cue from Gwyneth, we hunted down 17 equally fabulous black-and-white bags to add to your closet now.
