Apparently the woodcuts are from a tailor’s pattern
book, and the nudes are intended to show a sampling of
women’s body shapes, allowing the tailor to match
a set of dress styles to a customer’s own shape.
If anyone is interested in serious recreation of
clothing from the Middle Ages, a good start would be
with the series begun by Janet Arnold, “Patterns
of Fashion” vols. 1-5; Jenny Tiramani’s “17th Century
Women’s Dress Patterns”, and “The Tudor Tailor” series,
by Ninya Mikhaila and Jane Malcolm-Davies. None of
those are specific to 16th century Switzerland,
but all of them are thoroughly well-researched.
