## Summary

Men's long-sleeve sport shirt in a blue and grey windowpane flannel pattern, featuring a button-down collar and a classic fit.

## Description

Our Otto shirts are beautifully handsewn in Italy at eight key points — because otto is Italian for “eight”; get it? Hand-assembling the stress points allows for a fit that moves with you and makes for a truly special sport shirt, right down to the crow’s-foot button stitching that’s a signature of handwork. This one is made up in a deep, dark windowpane flannel and finished with a modified spread collar and lightweight, nonfused interlining for a soft, relaxed look. The cut is slim but never skinny, with a high armhole for mobility and a shirttail long enough to stay tucked in. (Sid likes it this way, but it’s easy to shorten if you prefer). It’s constructed with single-needle stitching at 22 stitches/inch, flat-felled seams, and thick 3.5mm Trocas shell buttons. Just like our other sport shirts — only a bit more elevated.
