Look to jet-setting celebrities for tips on how to stay stylish while you travel. Here, six lessons:
 Wear a cute hat: Rachel Bilson's fedora not only looks adorable, but it can conceal a bad hair day, especially if you're traveling uber early or catching the red-eye. Bonus: By wearing it on the plane, your hat won't get crushed or take up space in your luggage.
 Carry a cross-body bag: Emma Roberts keeps her hands free with a stylish cross-body bag, making travel essentials like that boarding pass and wallet super easy to access.
 Try a dress: There's no reason you can't fly in a dress, like the lovely Giuliana Rancic. Just pick a comfy fabric and toss a scarf or cardigan in your carry-on in case you get cold.
 Wear your heaviest items: Florence Welch stays true to her rocker-chick style when she's on the go in a leather jacket and black boots. On a practical note, these are items that weigh a lot and take up a lot of precious space in your suitcase, so wear them on the plane if possible.
 Toss on a cozy scarf: Jessica Alba loves to accessorize with scarves, especially when traveling. An oversized scarf will look cute and double as a shawl when you're in the air.
 Rock glamorous shades: Stars like Elizabeth Hurley never leave home without their sunnies. It goes without saying that a big pair of glam sunglasses will make you look cool and hide dark circles or the fact that you just don't feel like wearing any makeup. I find it easier to take a nap when I'm wearing sunglasses, too.
