When it comes to buying a suit, you probably know it’s important to sweat the details. And one key consideration you may not be thinking about is how many buttons should be on your jacket.

Three is probably best left to the Italian street-style gods, mod enthusiasts, and NBA players—it can be a lot of look to pull off. But one button suits, the less-often-found silhouettes of the suiting world, can be the secret weapon for guys looking to cut a taller, leaner figure just like John Legend (in Calvin Klein Collection) at the premiere of his new TV show Underground last night (above).
