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.
This jacket's fine-quality Merino-wool fabric was woven by Yorkshire-based mill Alfred Brown. A half-canvas construction helps it drape elegantly, while it moulds to your body over time, delivering a perfect fit.
