I found it does not quite work
I cannot get properly settled to work until I get my bathrobe off. Sure, I prefer working in the same ripped jeans or shorts I use for DIY, but not a bathrobe.
The shower thing is spot on - mine is after I have expended my useful brain charge and had my afternoon 3 mile run with the daughter. By that time USA has woken up and has started scheduling meetings so that nicely coincides with me being freshly shaven and with a new shirt when the video-conferences kick in.
The privileges of working from home I guess :)
