i have one for the guys:
why do brother never button the third button on their meeting jackets?
always buttoning the first two when they get up to do a part but never the last one. why?
That's the way suits are supposed to be worn. If you button the bottom button it bunches up when you sit down. It's mainly for that reason that we don't button the bottom. When brothers get on the platform some I know do button them up then unbutton them when they get off.
You have your jacket buttoned when you sit???
To answer your question, I don't know, I just did it cause that's how every other guy I saw wore their jackets. I only button the top button while I'm walking around, unbutton it when I sit. I didn't have a father to tell me the right way or not.
YOU ARE NOT SUPPOSED TO. In fashion men are only supposed to have the middle button of their jacket buttoned. But since many people don't like the way it looks they don't, they button the top two..
