What would a man's wardrobe be without these items? The answer is bleak. This isn't just about looking good, though. These are fundamental pieces for any man's wardrobe and you're going to need them all for the everyday suit, formal dress suit, or the more casual attire. That's not even mentioning what you'll need to wear at your job or on interviews! Let this list serve as your guide to help you never find yourself without anything to wear again. There is no man alive that doesn't own at least one suit jacket. This is one item that you will want to get right if you want to look like you know what you're doing. Ask any professional, and they will tell you the same thing: a suit jacket makes or breaks a guy's look - there's no in-between. The suit jacket not only adds another layer of style, but also covers up some of your more unsightly features: your gut and the fact that your shirt collar is too wide. It takes a skilled tailor to be able to make a great suit jacket - but it's essential for looking your best.
