Jessica Biel was spotted this week at LAX, boarding a flight to London with hubby Justin Timberlake, and we seriously can't get over the girl's perfect travel style. More specifically, we fell in love with her easy, single-breasted, menswear-inspired coat.

There are a lot of reasons to love this look. First of all, this coat is the perfect amount of oversize -- it's not too big that it overwhelms, but there's definitely a cool, slouchy vibe there. Second, it looks like just the right amount of weight for this chilly spring weather we're experiencing right now (at least over here on the East Coast!). And third, who doesn't love a coat in a gorgeous neutral bluish-gray? No one, that's who.

We're sure Jess can throw down for a super-expensive piece of outerwear, but for those not looking to break the bank, we came up with a few options that channel the essence of her chic coat. Click through the gallery to see them all.
