New Yorker here. Some of us with office jobs aren’t always wearing our work clothes on our commutes. We may be wearing something that can get sweaty and gross on the way, more comfortable shoes, etc. and change into office stuff when we get to work.

I’m a guy and usually wear a business-casual button-up shirt, but on my summer commute that shirt is in a bag or tied around my waist like a 1990s grunge-kid’s flannel while I sweat through an old T-shirt or A-shirt my boss will never see.
