3234-CSB - Rounder Cotton Suede - Black

A rounded collar is the kind of detail most people file under Ivy, somewhere in the 1950s and sixties, worn with a knit tie and a sack jacket. That era was itself looking backward. The club collar goes back to Eton in the 1860s and ran through dress shirts on both sides of the Atlantic into the early 1900s, which is the period the Rounder is actually pulled from. Post O'Alls skipped the revival and went to the shirts the revival was copying, which is why the collar here sits shorter and rounder than the Ivy version most people picture.

It is the rounded-collar cut of the Original BL Shirt, new for Fall/Winter 2026, and the cloth is a cotton suede. That name describes the finish rather than the fiber: the surface is brushed until it carries a fine, dry nap that catches the light the way real suede does and feels soft and slightly chalky in the hand. It comes prewashed, so none of that has to be broken in. Made in Japan.

A variance of +/-.5" is within tolerance.

Fit Notes: As with most Post O'Alls fits, these are on the roomier side so Tommy is wearing a medium. The shirting is meant to layer nicely under their oversized jackets. Of all their shirts though, the roudner seems to be the truest fit. We would recommend snagging your true size if you want a tailored look like the photos. If you want more room, size up. Tommy is 5'9," 160lbs with a 41" chest.
