I have always been a tee shirt and board shorts/jeans kind of guy. I own exactly one necktie, and it's currently wrapped around my Nightmare Before Christmas tree as garland (because it's a Jack tie). I'm fortunate enough to work for a company who's dress code is "you must be dressed", basically, and the C-levels all show up in more or less the same thing I wear on a daily basis. Generally on the weekends I'd be in a tee/shorts/Tevas (no socks, you filthy heathens!), so even today I wasn't far off of that, just grubby and disheveled. But I'm with you. My time is "IDGAF about how I look as long as my underwear are clean" time. Evidently that's just a bit too casual for some of the older crowd.
