Charles Tyrwhitt shirts are world-famous for more than one reason: quality, perfect fit, and options. Choose from work shirts that dress you for meetings, tuxedo shirts, and weekend shirts. Order them your way; collar, cuff, size, fit, and style.
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.
