I'm not really sure what you mean by pinny. My aprons go over my head, with a bib, then the waist strings wrap around and tie in the front. I remember my Mum had some that were just waist-down, and I always thought they were a bit useless!
I use one in the kitchen most days, and save the older stained ones for bathroom cleaning. I have a men's denim shirt that I use as an overshirt while gardening.
