We went to the opera on Mon. The man sitting next to me in not-cheap seats was wearing a chalk-stripe coat and cords. The coat had plain buttons and I would consider it a suit coat.
I looked around at the next intermission and noticed that several men were wearing jackets that looked like suit coats with unmatched trousers. Is this a new trend? or a borrowed coat?
It raises the question about suit coats and odd jackets. What are the differences?
A blazer is generally a navy worsted with metal buttons--any other specifics?
