Charles Tyrwhitt luxury shirts are made from the highest quality fabrics for an unrivalled smooth, soft feel: two-ply 120s and 140s yarns and Egyptian cotton. As well-dressed gents know, detail is everything.
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.
