Right, while we’re on the subject, I’ve been wanting to ask for a while - crotchless knickers. I know they’re for sexy time these days, I’ve got that far, but historically I believe they were worn by ladies 150-odd years ago for practicality when going to the loo, ie hiking up a few layers of skirt etc then not having to pull pants down as well. I don’t think I understand them generally. Anyone?
