This will be a short one. Black cuffed knee length pants, elastic waist. Overall, the pants are meant to have even less impact than the shirt. They are the afterthought of the outfit, really.
I used black apparel canvas (NOT outdoor/upholstery canvas). The waist has a tabs with a belt slider on the side seams for fit adjustment, and elastic in the back waistband for movement and comfort. I know, I know - elastic is not exactly period appropriate. But, as a regular and serious rennie myself, there have to be considerations made for comfort when wearing costumes all day and in possibly extreme weather situations. The buttons on the knee cuffs were purely decorative and not strictly necessary, but it's these little things that make it special.
Sorry for the photo quality below! The camera adjusted the light settings to the white table, and the details of the black fabric were lost unless we messed with the light balance after the photo was taken.
Ta da! The finished product. The dress dummy is so helpfully holding the pants up with her non-existent arms. ;)
Twins each with half a brain in reality; the other half displayed here!
