I don't care for the suit to be honest. That said, I do dress a hair more formally than most when given no direction what to wear but even then I am dressed for comfort.
For example, for class today I wore a pair of cargo pants (can't have too many pockets), a collared button up shirt (I didn't tuck it in of course because I was not trying to be formal in the slightest. In fact, I wore this shirt because it was going to be a bit cool outside and was likely to rain), a pair of brown boots (which are, somehow, more formal than regular sneakers, but less formal than an actual dress shoe. They are, however, more comfortable than the latter and more generally useful than either) and a longish coat (beyond the hip but above the knee. I believe the style is called a car coat). Given that the average person (who was not employed by the university) was wearing jeans, a t-shirt and a hoodie (or something roughly equivalent) I was actually dressed fairly formally as I could, at a moments notice, tuck in my shirt and unroll my sleeves and be presentable for most environments.
Before the day ended, I cursed the fact that I did not bother bringing any lighter coat with me to South Texas as a coat for the purposes of warding off the rain is all well and good but if it isn't raining and it isn't really all that cold, it just leads to a lot of needless sweating.
