We like a tartan shirt that can go year-round, not just for holiday… this one is festive for sure, but can be worn with khakis or white jeans in the shoulder months for a less on-the-nose look. The collar’s got a particularly nice roll to it with just the right amount of “bloom,” plus an extra button at the back of the collar, which is an old-school detail originally designed to keep your tie in place. (We just like the way it looks.) The cut is slim but never skinny, with a high armhole for mobility and a shirttail long enough to stay tucked in. (Sid likes it this way, but it's easy to shorten if you prefer.) It's made with single-needle stitching, flat-felled seams, and thick, 3.5mm Trocas shell buttons.
