Once again, J.P Ryan's riding habit pattern proves to be the best available =)
I changed the orientation of the pockets and the flaps for preference, but other than that there were no changes to the pattern itself. The instructions are more modern, but if you're familiar with 18th century construction techniques, it's nothing to just assemble it the way you want.
The "Sporting Ensemble"?
I've seen many images, especially paintings, or so-called riding habits that really didn't look feasible for a woman to be wearing on actual horseback. I think riding ensembles were quite popular for other outdoor activities, like lawn games, picnicking, etc. I got my impression here from a fashion plate that indicated a silk taffeta petticoat with a riding coat. I can't imagine anyone would attempt to ride a horse in a taffeta petticoat! That would be the worst fabric imaginable for that purpose, so it was definitely the riding habit "look", but not the function.
[of course we do this today as well. It's common for people to wear yoga gear when they do not and have no intention of doing yoga =P]
