A suit jacket has pockets, especially inside, and it's structured. So it gives you a much more crisp look than a button shirt. Also, it's just a jacket. Why are people so afraid of a jacket? Remove the jacket and you're left with just regular button up shirt and trousers.

This is why people should be used to wearing button up shirts and trousers, and tucking their shirts in. That should be a basic requirement for any man at any public places. Once you've got that down, a suit jacket wouldn't feel all that "muh dressy".

And it doesn't always have to be a black or navy blue jacket. Suit jackets, blazers and sports coats come in every color and pattern under the sun. Stop putting suits on a pedestal. Just treat them as a tool to get a structured and crisp look and you would feel fine wearing them.
