You can never go wrong with a crisp white shirt under a suit coat – it’s timeless, classy, and will always match whatever suit color you have. Regardless of whatever color shirt you go with, it’s important to get a form-fitting undershirt to wear underneath it. Also, your shirt shouldn’t be too tight or too loose. If you’re looking to up the formality of your suit, you can always add a vest; however, vests are not a required part of the outfit.

Belts, Shoes, and Socks

It’s important to not overlook the accessories for your suit – belts, shoes, and socks are just as important as your pants, shirt, and suit coat. One easy rule to remember that will make your outfit look cohesive is that you should match your belt to your shoes; for example, if you’re wearing a brown leather belt, opt for dress shoes, like Oxfords or brogues, in a similar hue. 

As far as socks go, you want to make sure they are long enough so that when you are sitting down, no part of your legs show. An easy way to test out if the length of your socks is the right length is by simply sitting down and crossing your legs both ways to see if any skin shows. If you can see any part of your legs, grab some longer socks, and never, ever wear white socks with a suit, or no socks at all. 

Ties and Pocket Squares

One rule of thumb that you should always follow is that your tie should be darker than your shirt. For example, if you’re wearing a black shirt with a yellow tie, you’ll look like you’re heading to your 2006 prom – and no one wants to look like that. Another thing to remember when picking out the right tie to wear with your suit is the length of your tie; it should hit at the top of your belt buckle or at the waistband of your pants. Width-wise, you’re gonna want to make sure that your tie is about the same width as the lapel on your suit jacket.
