I've heard of 19C women in crinolines standing still with legs apart (no knickers then) A pair of drawers, when they came in, were just that, two separate legs tied on round the waist, so they would be pullasideable.
I also heard of a 19C man (I think an author, but can't remember who) who claimed he was traumatised right into his adult life because as a boy his mother had done this while out walking somewhere with him, and the embarrassment caused him untold mental anguish! Self-obsessed little sod, giving birth to him was probably what made her need to go at once, with no public loos for women and home a long way away!
