A bit of a a sweaty etiquette question for you all.
I'm going to an interview and I plan to wear a boiled wool jacket (my only jacket and ca't afford another) and a smart t-shirt underneath. I always get nervous at interviews, and don't want to spend the entire time being conscious of over-heating and sweating into my jacket. I think I'll be better off taking the jacket off, but the question is: would that come across as too casual? should I keep my jacket on and suffer?
I know it's a bit trivial but if anyone has any advice/views, it would be great to hear them. Also, if there's a better place to post this, let me know please.
