    I’ve been teaching college for many years, long enough to note the steady relaxation of attention in matters of student dress. I’ve long grown used to the tom jeans, flip-flops, shorts in the dead of the Maine winter, and ball caps worn backward. Still, I took note recently when one of my students showed up in pajama bottoms. I couldn’t help stopping him and remarking, “Did you just roll out of bed?”

His response: “Five minutes ago.”

I'm familiar with the school of thought that says that how students dress is irrelevant, so long as they’re learning. I deposit it in the same category as “Grammar and spelling don’t matter, so long as they’re expressing themselves.” Perhaps. But I also wonder about the wisdom of confusing the line between bed and desk. I should think that dressing properly before entering a formal environment, such as a college lecture hall, is a sort of visible reminder to oneself (and one’s teachers) that impressions are important and that we have come together to get down to business.

I smile when I think back on the occasions that my parents associated with needing to look presentable. Once, when I was 11 and my brother 9, my father announced that he was taking us into Manhattan (just a subway ride away) to see the film of “2001: A Space Odyssey.” My brother and I were happy at the prospect, but were soon deflated when my father directed us to put on our best clothes, including jackets and ties. “But why?” I begged, not wanting to change out of my comfortable jeans, T-shirt, and sneakers.

“Because,” he said, “we’re going to New York. Other people would observe and assess us based on our appearance.”

So yes, I’m all for freedom of choice in matters of dress, and yes, I do want my students to be comfortable. But I also want to pay my respects to those students who believe that appearances count.
