The sleeves reach to the elbow and are 30.4cm long from armpit to end while the total length of the shirt is 71.1cm and its weight 8.84kg.

This is a rectangle of mail with a square hole in it large enough for the head to fit through (figure 1, below). Enlarge this piece until it covers the top of the arms and the front and back of the trunk to just under the armpits (figure 2). As you are building this piece you will have to add a set of expansions over each shoulder. These run from the collar bone at the front to the top of the shoulder blades at the back (figure 3). They are there to form a bag enabling the shoulder to move without straining the links. The original suit has nine expansions in each set with one idle link in every other row.
