There’s a difference between pajamas and comfortable clothes though. One can wear jeans, sweats, workout clothes, or other things that you could leave the house in, while not getting into full “office” attire.

I think this is a critical item for working at home. You want to be wearing something that you wouldn’t mind answering the door in, or if you had to run an unexpected errand. (and contrary to what the People of Walmart site shows, it is not appropriate to be doing those things in pajamas).
