Some guys wear a suit every day for work. Most likely, these fellas know what to look for in a good suit -- they're surrounded by them, and they've probably suit shopped more than once. But a lot of men wear suits only for certain occasions -- weddings, funerals, and maybe interviews -- and these are the guys we're talking to today.

If you're only going to have one suit hanging in your closet, make it the right suit. Whether you choose one that's hot or hideous, you're going to be spending a chunk of change on it, so you might as well look your best. And, take a cue from GQ -- dress like Cary Grant.
A solid gray wool suit paired with a light shirt and dark tie is classic, simple, and gives an air of power. Plus, with a solid gray suit, you always have the option of playing around with different ties and shirts as you become more confident in wearing it.

Fit, however, is just as important as the style you choose. Check out GQ's video on buying a suit (above) for expert tips on everything from lapels to vents to tailoring.
