The Garrison Shirt is cut in the same loose fit as the Atlanta Shirt, offering a relaxed, easy silhouette that works comfortably through spring and summer.
Finished with a set-in sleeve construction, it allows the fabric to drape naturally off the shoulder, creating a softer line and a more fluid shape through the body.
Crafted in our Corbet Brown quality, it’s made from a soft striped cotton with a smooth handle and relaxed feel. The understated stripe adds depth and visual interest while remaining easy to style.
An effortless seasonal staple, the Garrison Shirt pairs just as easily with casual pieces as it does with more tailored looks, making it a versatile option for everyday warm-weather dressing.
- Loose fit overshirt
- Fits true to size, we recommend taking your usual size
- Model wears a size M
- Model measures: Chest 38" / 96cm, Height 6’2" / 188cm
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.
