The three-button suit
Best for: The three-button suit is an excellent option for men taller than six feet because the buttons on the jacket reach higher up on the chest, making it more comfortable and visually appealing on taller men. The three-button suit jacket is also an option for waistcoat enthusiasts.
Trend factor: A three-button suit has a ‘60s-mod feel to it. Accordingly, it has recently made a comeback with several influential designers showing three-button suits in their fall 2009 collections. Although they are not as timeless as their two-button cousins, three-button suits are relatively trend-proof -- so long as you purchase a classic-cut model.
How to wear it: The recent trend for wearing three-button suits has been to fasten the top two buttons, but this can make the lapels on some suits appear unusually short, and you run the risk of appearing somewhat awkward. If you don’t naturally have an abundance of confidence, close only the middle button for an elegant look. Whatever you do, never close the bottom button; doing so will distort the drape of the fabric. Additionally, though you will never do up all three buttons because it will create a stiff look, you should be able to close the buttons on a good suit without pulling or stretching the fabric.
When/where to wear it: Three-button suits are a good alternative to two-button suits for office wear, particularly if you’re looking to stand out slightly from everyone else in the style department.
