Thanks to everyone for contributing your knowledge to this idea.

OC Richard, I didnt know that they were goat hair. Where do you get one of those today? And thank you for giving us an example in modern wear of that style sporran

NorcalPiper, I think you and I are on the same track. You worded it much better than I am able to.
The kilt is a historic garment that has survived time. Hair sporrans and patterned (argyle/diced) hose are also historic but have been moved from the everybody(or at least some) and everyday, to the very formal and very seldom worn group. While wearing the kilt, I'd like to bring some of those traditional items back to everyday modern use.

As many of you have stated, those prints are "dressed up" and made to express the painters view and what others want to view. I acknowledge that and have taken those images with a grain of salt. There is some value to them though. In that time, some of the folks wore goat hair sporrans and some wore patterned hose in informal settings.

Still, why are these things being worn by so few today?

Thanks again
