I don't know what the students made of it. This being Britain, even if they did notice it, they'd regard it as attention-seeking and therefore wouldn't attend to it at all. My wife doesn't like it, but didn't notice I was wearing it until half an hour after she first saw it, so it can't be that bad.
I like it myself, but it's too short. If I raise my arms, it comes out and I have to tuck it into my trousers again. I may have to get it in a larger size.
Gawd knows what it's going to do when I wash it...
