If you have looked into the history of trousers, chances are high you stumbled across the find from Thorsberg. They are remarkably well-preserved, and they have a very curious pattern that results in a nice, form-fitting, leg-hugging fit. (Which means that you can show off your legs as the wearer of these trousers, and enjoy the view if you are a spectator.)
As a result of a research project of these trousers, there's a 3D simulation of them done in sketchfab, and you can have a look at them from all angles. It's fascinating, and I was thrilled that the model looks very much like the reconstructions that I made a few years ago when worn by the Most Patient Husband of Them All.
You can take a look at the model here, and there's links to the research behind it and the academia profiles of the researchers as well.
