Obviously when it comes to you standing or walking around then obviously you want to keep your suit jacket buttoned up. Depending on whether its a two or three button suit you only ever do the top buttons up. It just fashion suicide to do so. So when it comes sitting down then you absolutely 100% have to unbutton your suit jacket. I’ve seen men do everything perfectly right in terms of their outfit and then sit down and look silly with their suit jacket still buttoned up.
Good question, you have to unbutton your jacket because otherwise the jacket will bunch up or be pulled around and undoubtedly it will completely lose the shape of the jacket. A suit jacket with no shape just looks cheap – don’t do it.
So if any of you have watched Crazy, Stupid, Love then you know Ryan Gosling is like the alpha male when it comes to talking to women and looking great doing it. In the picture he stands there with his suit jacket buttoned up and then as he pulls up his chair to sit down he unbuttons his jacket perfectly.
