Two is eternally timeless. Three seems to come and go. But what you don't see as often is the single-button suit. The rakish style not only strikes a balance between the classic and the modern, it also takes the guesswork out of which button to fasten on your jacket. Perhaps that's why so many brands are putting them out for the coming season. Often found on more formal styles like tuxedos, the slimmer notch lapels and natural sloping shoulders of the jackets featured here lessen the suit's formality—making it look less like a tux and more of a look that says simplicity, nonchalance and pure unadulterated cool. Not to mention, the one-button is a good option for guys who want to add the illusion of height to their look. The jackets on these are cut a touch shorter and slimmer, plus with the added length of the button stance, it makes for a longer, leaner appearance. And unless you're Lebron James, we could all stand to look a little taller.
