Champlain

Standard letter sizing, cut to a modern rather than a slim pattern - trim through the body, with a shoulder that sits where it should and none of the compression of a true slim fit. Knit polos and tees have a little give and settle after a wear or two. If you fall between sizes, the deciding question is usually layering: take the smaller size for a shirt worn on its own, the larger if a cardigan is going over the top.

It is the open, flat collar you see on holiday shirts: no stand at the back, with the two points lying flat against the chest so the neck stays open without looking undone. It suits a relaxed cut and warm-weather cloth, which is why it turns up in corduroy, linen and lightweight cotton rather than crisp poplin. Wear it untucked, and leave the top buttons alone, because a camp collar loses its point when it is done up.
