WHAT ARE THE BLAZER BUTTON RULES IN AMERICA?
Blazer Button Rules
With one-button, three-button, and double-breasted suits and sport coats floating around, it can be hard to know what to button when. Here are the only rules you need to know:
The One-Button Jacket
This one is easy; it should be buttoned while standing and undone when you sit down. Leaving it buttoned can stress the fabric and make the jacket feel a bit uncomfortable. Relax and loosen that button once you have a seat.
The Two-Button Jacket
The top button is all you need. The two-button jacket should never have both buttons fastened.
The Three-Button Jacket
The three-button suit comes with a simple rule: "sometimes, always, never." It means you should sometimes fasten the top button (if you feel like it), always fasten the middle button, and never button the third.
The Double-Breasted Jacket
Fasten every button save for the bottom button, though even here there is some leeway. English royalty and dandies have been known to fasten every button when they feel like it. You can keep your double-breasted blazer buttoned when you sit.
What about the Shirt and Vest buttons?
When wearing a necktie, all buttons from your neck to the bottom of the shirt should be buttoned. If you decide to leave the tie at home, you can either button the shirt to the top for the "air tie" look or leave the top two buttons open to play it more casual. Never leave more than two buttons open though, unless you want to look like Keith Richards, which spoiler alert: you don't.
If you decide to throw on that three-piece suit, keep the bottom button of the vest unfastened. Though Anglophiles claim that fat King Edward VII created this look out of, um, necessity, it also helps keep added stress off the fabric, which is good for your vest and your comfort.
