The Garrison Shirt is cut in the same loose fit as the Atlanta Shirt, offering a relaxed, easy silhouette suited to warmer weather. What sets it apart is the set-in sleeve construction, which allows the fabric to drape naturally off the shoulder, giving the shirt a softer, more fluid line through the body.
Crafted in our Byrne Blue quality, it’s made from a lightweight micro-gingham with a subtle crepe-like touch, adding texture and breathability while remaining refined.
An effortless wardrobe staple, it works just as well styled casually with denim or shorts as it does paired back with more tailored pieces, making it a versatile option for relaxed summer dressing.
Size Guide
Our production team have hand-measured each garment, so the sizes you see below are reflective of this style. Compare the sizes below to one of your favourite fitting garments at home to find your perfect size.
Measurements are taken from the outside of the garment, lying flat and then doubled for your convenience. Therefore, a 20" chest lying flat will measure 40" around.
