Jacket looks a bit too worsted to me for open collared gingham. Additionally, I don't like the square with the shirt, it almost feels "matchy"? I feel like good ole cream silk would look good here. Maybe something similar to what you have with light colors?
I like how your jacket fits.
Anytime you guys get into the specifics of a type of fabric my eyes glaze over and I skip down the page. To me, this is a navy blazer. So would you kindly expand on why worsted and gingham don't jive? Are you saying it looks like I'm wearing a casual shirt with a suit jacket?
I should have probably just grabbed a plain TV fold white linen, but I had done that all week. I don't have cream silk, but I see where you're going and agree it's bordering on matchy.
