Raise your arm and bend it slightly at the elbow (like you're looking at your watch). Using a tape measure, start at the centre of your back, just below your collar. Measure from here to the end of your shoulder and note down the measurement. Next, measure from the peak of your shoulder to your elbow, and finally, measure from your elbow to your wrist (where you want your cuff to sit). Add all three measurements together to calculate your sleeve length.
Cotton and linen are a classic partnership for good reason. This shirt combines the best of both fibres to create a breathable fabric that permits airflow, naturally absorbs moisture and has higher crease-resistance than pure linen.
