Now you Know: Which Suit Button Should I Use?

Why you shouldn't button up both buttons on a two-button suit or sport jacket.

First of all, doing up only the top button looks better.

Secondly, leaving the bottom button undone adds to the movement of the jacket when walking or with your hand in the pocket—the jacket hangs better and moves more naturally.

Thirdly, doing up both buttons will force the jacket to hug your middle, and most guys just don’t need that.
