So do most of my peers, and I'm 40.

A few of us wear suit jackets now, but I think that's just to stand out from the crowds of jeans and t-shirts that became my generation's accidental dress code.

(Though perhaps I'm just projecting; on the rare occasions I wear a suit jacket, that's what I'm thinking).

oh it was no accident. it took a lot of determined laziness and disregard for the casual Friday corporate culture BS by smarter than most people to change to rules.. band shirts, cargo shorts and skate shoes beats button downs, khakis, and leather loafers all day err day. got a not so casual work event to attend? bust out the nice grateful dead shirt, black zip up hoodie, and the jeans without the holes, and own it hard

I’m mostly with you but

1) blazers, specifically, are awesome, they’re wearable purses that also make you look sharper. They’re a superior version of the open button-up shirt I’d wear in high school because it was trendy back then and which also had (less well-realized) utility and useful-in-a-pinch value, and

2) loafers are the best shoe for everyday not-very-active stuff, and it’s not a close call. Slip on! It’s insane that they’re considered even a little dressy. A small miracle.

Except if you're an active person. Blazers don't give you full range of arm motion unless they are laughable baggy or made of some weird stretch material that looks cheap. Loafers are sub-optimal for running up stairs, catching the train/bus that's about to leave, or moving heavy things.

Or if someone has set the HVAC for a temperature above 60F.

Action back. (Yes that’s the actual name)

Look at Indy’s suit early in Crusaders for an example.

I don't care about age, 50+, blue jeans, black tshirt, sometimes with a Mario print, hoodie when it's colder. I dropped the pink chucks though.

Blue jeans? Please give slacks a look... :P
