The shirt has a "granddad collar" — which is to say, a collar stand, but no actual collar. Quite why it is named for the father of a mother or father is unknown, but it is something that can be made to look smart or casual, depending largely upon whether the top button is fastened or, indeed, unfastened.
The shirt is intended to be worn tucked or untucked. That's both. It has a fitted shape, so when tucked in, it rolls tidily into the trouser — but it is also casual, so when untucked it won't look like you've stepped out in an office shirt. It is a standard length: falling a couple of inches below the belt-line on most people.
The shirt has a front of six horn buttons — each of them, in their own natural way, different from one to the next. Meanwhile, every significant seam on the shirt is what's known as a single-needle, lock-stitch, French seam. They take twice as long as standard seams, but look nicer, wear better, and last longer.
The shirt has a chest pocket, with a narrow section on the inside-edge — for a pen, pencil, or chip fork, say — which is established with a long bar-tack. Bar-tacks also appear at the top corners of the pocket, for great strength, as well as several other parts of the shirt subject to the most wear and tear.
This is a flecked merino woollen medley of grey and assorted whites. Substantial, yet smooth, and, quite importantly for a woollen shirt, not in the least abrasive; it’s the merino that sees to that. It also sees that the shirt will happily hold its shape from wear to wear. Doesn’t ask much by way of ironing, in other words.
