The key is keeping the rest of your lines clean. Sienna pairs her on-trend, wide-leg Sea New York jumper with a simple white ribbed turtleneck from Acne Studios, plus a pair of sneakers and a no-nonsense tangerine Prada tote. Throw in a pair of funky Maryam Nassir Zadeh sunnies, and you're good to go! There is no other way to show up at LAX, ladies.
