I know that coveralls are meant to keep your clothes clean when you're doing a dirty job, but once in a while, I find them quite compelling.
If you had a well-fitting pair of coveralls, you could slap them on over your underwear for a great lazy outfit. Nope, no dealing with pants today, you might say. No belt, you've got shoulders to keep these things from drooping. There's no tucking in, there's no shirt coming untucked. And, at the end of the day, it's easy out. Never have work clothes shed so easily.
Think about it. I know that no good change happens so instantly, but they could become a good addition to every person's wardrobe.
