The most profound recent development in men’s clothing concerns the millimetric adjustment of a garment first sold in 1900. In January, Brooks Brothers issued a redesign of its oxford-cloth button-down, the shirt known commonly, and not quite insufferably, as an OCBD.

The upgrade to mother-of-pearl buttons, the addition of side gussets to the shirttails, even the disappearance of the breast pocket — these tweaks are no big deal, unless you are an emeritus professor wondering where now to stick your reading glasses. The removal of the collar’s interior lining, however, constitutes a major moment in the history of minutiae, as it reinstates a first-rate collar roll.

With its points buttoned down, the unlined collar spreads and bends at its front edges to form an elegant bell curve, or maybe to slither a bit asymmetrically — a casually dashing soft contour among the strict lines of traditional men’s wear.

This is the sort of detail in which God is said to exist. Philosophers of the Ivy League Look liken particularly dramatic collar rolls to the silhouettes of angels’ wings.
