Surprising. Well, someone's gotta do it, I guess. ;-)
We have folks in retro 80s video game t-shirts and shorts in the Dev team. They think I'm stodgy in my jeans and polo and greying hair. Haha.
I always thought dressing up for church was the worst/most pretentious. For a group of folks tasked with serving the poor, it never made any sense to me.
I went out of my way not to overdress in the more formal churches I've attended over the years so the parents who were struggling just to get by didn't feel like they needed to buy fancy clothes for the kids all the time as they outgrew them. Or themselves for that matter. Certainly ever a suit and tie, although many did that.
Probably why I ended up working at homeless shelters more than sitting in pews full of well-dressed people. No offense intended to anyone who finds that the well-dressed pew sitting works for them. Just not my cup o' tea.
Much of the time I attended those types of places, I was back at the mixer board in jeans making sure the sound system didn't sound like crap anyway.

A button down shirt or nice polo on top kinda like doing a videoconference from home. Nobody sees your pants through the sound room window or over the low wall.
