I've been commuting to work for 18 years in "office-casual" type slacks such as Dockers. I've learned to *always* use good cuff restraint, especially on the right leg. I usually get 2 to 3 days out of a pair of pants except in the hottest weather (I'm in Chicago).
The longest part of my commute is between 3 and 5 miles, depending on circumstances. The total distance is about 50 miles each way, so obviously it's "multi-modal", with the biggest part on heavy rail. I have done the entire round-trip a few times on my folding bike, but a "bike-to-work Century" is not sustainable.
The latest wrinkle (no pun intended!) is that because of the coronavirus, I will be wearing scrubs at work (I'm a dentist), so I will have a little more flexibility in choosing comfortable biking clothes.
My goal is to complete 20 years of bike commuting before I retire.
