16th Century - Basic Doublet Pattern

You'll need one and a half to two metres of fabric for both the outer (brocade, velvet, wool etc) and the lining (linen).
The lining body pieces are slightly longer than the equivalent outer pieces, so as to allow for eyelet holes which attach the doublet to the trousers.
Using the same pattern without the sleeves will produce a jerkin which can be worn over the doublet (make it slightly larger, obviously).
