It just occured to me, that todays clothing industry is still stuck in Victorian times, in some ways. In particular, the right/left-handed zipper/buttons thing. Mens clothing gets zippers that can be done up right-handed, ie the flap of cloth over the zipper is on the left, leaving it accessible from the right. Womens is the opposite way around, this was originally because women didn't dress themselves, but got dressed by their servants, and thus the zipper/buttons/whatever were right-handed ...
