Timelessly American, but with origins in France, chambray is always a perennial favorite for spring. Its undeniably soft and casual in spirit — a virtual wardrobe no-brainer that goes with everything. The fabric truly was borrowed from the boys, first used for U.S. Naval uniforms in the early 1900s and famously worn by Paul Newman in Cool Hand Luke (so you know it's got cred). Sartorial options have evolved beyond the classic baby-blue button-down shirt (but should you need an upgrade, Levi's one-pocketed shirt would be a wise choice). Now, jumpsuits, polka dots, Bermuda shorts, and pajama sets (wear the shirt with a military green pant and you're weekend ready) are all fair game. And for the ultimate chambray enthusiasts, Topshop's tailored blazer and pant, when worn together, look smart without veering into punchline territory. Click ahead for thirteen ways to incorporate the easy fabric for season ahead.
