Paul Newman originally made the Chambray shirt famous in the film Cool Hand Luke.
Typically if you attempt to emulate Paul Newman’s style you will get by just fine in the sartorial sense however in the case of the Chambray shirt they are now a hot spring/summer trend and are completely back in style. Chambray, for those wanting to know, was first used in Cambrai, France and is a lightweight cotton cloth great for warm sunny days.
I recommend taking a peak at the GAP where you will find a few options for Chambray Shirts. I recommend the item pictured on the model above. It’s fabric, cut and white buttons are what got me. Notice how the model is trying to channel his own internal Paul Newman?
