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.
This here shirt has a standard collar, which isn't to say a collar in any way rote or jejune. Rather, it is a collar free from buttons and tabs and from efforts to strive either this way or that. It is a collar that is balanced. Its size: balanced. Its angle of opening at the front: balanced. The curve of its points: balanced.
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.
The cuffs of the shirt are unapologetically tight, so the sleeve can't step over the line that is the start of the hand, and they fasten with a single button. The corner of the cuffs is gently curved, echoing the collar.
This is a corduroy which is middle of weight and narrow of wale. It is a very soft cloth, particularly its interior, but — cord being a traditional working cloth — is exceptionally hard-wearing. And, despite being soft and warm on cooler days, it is eminently breathable, and so really rather good all year round.
