Bright scarlet puffing protruded from the slashes in his shabby fustian doublet
Obviously, we are talking about someone from 16th century, a doublet not being a contemporary garment. My problem is this "puffing". It seems that this doublet has some slashes -I infer verticals and as a decoration-, from which is exiting something of scarlet colour, this something is "puffing", but I've no idea what kind of staff puffing is here.
Thank You for any assistance.
Men's doublets and women's dress-sleeves in the late 16th through the early 17th century were often padded - several laters of fabric, one over another. The top fabric was then slashed, and the underlying fabric pulled through as though puffing out, giving a contrast in colour.

Your quotation mentions fustian. Someone wearing fustian is most unlikely to have intentional and fashinable puffing. It was one of the cheap woollen fabrics.
