But, you wouldn't be able to pull yer knickers down properly if it only opened at the crotch.MML - In the early 70's I had a couple of figure hugging (when I had one) stretchy body tops that had press studs between the legs. They were actually great for wearing tucked in trousers and skirts because there was no 'ride up'.
Just wondering if that could be a solution for jumpsuits - like a baby's romper suit, with buttons/press studs in the crotch - they wouldn't be noticeable and more practical than navigating grubby toilet floors.
Especially if you had a drink or two or five on board....I remember those, it was ok when you put them on at home but when you were in a public loo trying to keep everything else off the floor it was neigh on impossible to reach around to get the flap in place and do the snaps.
