Every guy should own at least one suit. A well-fitted suit is necessary for any formal occasion. Coming right off the rack, a suit is not going to fit your body perfectly. That being said, it is in your best interest to have your suit tailored.

An important aspect to consider when trying on a suit is how the shoulder seams line up with the ends of your shoulders. An alteration to the shoulder seam is the most expensive aspect in tailoring.

A suit should fit snugly to your body and should not strain at the buttons.

Arm holes should allow movement but should not be large enough to give a sloppy appearance.

A suit’s length should be long enough to just cover your seat. The pants should not strain or be loose, but outline the shape of your body. At the bottom of the pants, they should only have one break (the fold above the cuff when the pants hit the shoes). Too many breaks and the pants look baggy.

Inexpensive suits can be found either at a thrift store or Goodwill. After you tailor the suit, it will look more expensive than it is.

If you’re buying your first suit, get a navy blue one. It’s called the “Four Season Suit” for a reason.

Since the dawn of their existence, suits have been worn in a particular fashion: together with a button-up shirt, a tie, and a pair of dress shoes. But we are in the 21st century, pieces of suit can—and should—be broken up to give a more contemporary look.

A suit can be worn for semi-formal occasions. In a casual setting, comfort is important.

Thus, wear items that provide comfort but do not sacrifice style. Pair a blazer with jeans or colored trousers.

Replace the button-down shirt and tie with a v-neck t-shirt. Instead of the traditional dress shoe, try boots or sneakers for that go-anywhere type of look. A suit is a priority in every man’s wardrobe because it can be worn in countless ways.
