Actually, I miss wearing "work clothes", I like changing out of shirt and tie into jeans and t-shirt when I got home, it drew a line under the working day. Now it all blends into one (including working after hours...)
I used to feel this way for a long time actually. I had to have something to demarcate 'work time' from 'home time'.
What I found that worked for me, however odd, was the notion of 'work shoes'. I'd wear a pair of 'work shoes' when I was working, and swap them out for sneakers when I was finished working, and it achieved the same effect.
That worked well until I discovered Johnston & Murphy loafers anyway, which turned out to be actually more comfortable than my sneakers, but now I'm pretty much working all the time anyway, so it's .. okay?
