My dad wore two shirts a day. White, starched, cotton and linen blend shirts. My dad, at best rumpled-looking, felt it was essential to maintaining a professional appearance.
When I was very small my mother spent a lot of her time ironing my dad’s shirts (I don’t ever recall our household help doing any ironing). Later when we had a bit more money, my mom sent my dad’s shirt to the laundry. But that still meant trips to the laundry several times a week if not on a daily basis. On net it probably reduced my mom’s workload but just as importantly it changed the nature of the workload.
When permanent press became widely available and affordable in the mid-1950s, it changed her life.
