My husband can sometimes go days without seeing my in civvies. Sometimes he just sees me in PJs, and he may well think I go the whole day in my PJs (or tracky daks - but let's just keep that between you and me), but he'd be mistaken. As proof, I've embarked on a wee 10-day project. It involves bad pictures of myself and whatever I happen to be wearing that day. Here's day 1 and day 2. 
Here's proof that I still do function in society. It's totes true.
