One of my other interests is the history of costume, & in the 60s/70s an amazing researcher took patterns from surviving garments, including those European Royalty & nobility were buried in, see volume 3 - Janet Arnold Patterns of Fashion series Parts of the tomb clothing had rotted over the centuries.

here's one of the garments she measured - scroll down to "Die gruftigsten Klamotten" (Dorothea Sabina von Nuremberg)

Others researchers also did so, but I didn't have their books.
