The Machinist shirt is another gem from Freemans. Short loomed Japanese cotton paired with Italian mother of pearl buttons makes it an obvious choice for adding to your closet. The button on the upper sleeve to keep it rolled up for doing all that hard work we do is a great detail.
Don't fall into thinking you can only wear a suit as nice as this formally. I'd even wear it with the Machinist shirt and those Alden Roy boots from Context for a nice look.
