#1) Match Socks with Trousers
The golden rule of choosing dress socks to wear with a suit is to match them with the color of your trousers. The general idea in doing so is to make your socks and trousers blend together. If you wear black trousers, for instance, wearing a pair of black socks will create a cleaner and more uniform appearance. On the other hand, wearing black trousers with a pair of white socks will create an unusual and awkward appearance that makes you stand out. To prevent this from happening, always wear socks in the same color as your trousers.#2) Choose Thin Lapels for a Modern Look
Unless you're going for an classic, old school look, it's best to avoid wearing a suit jacket with wide lapels. As you may already know, lapels are the folded sections of fabric on suit jackets and coats. They are created by folding the front edges over; thus, creating an double-layered area of fabric on the front of the jacket. Different suit jackets, however, have different sized lapels. Generally speaking, wide lapels offer an old school look, whereas thin lapels offer a newer and more modern appearance, the latter of which is preferred by most fashion-forward men.#3) Your Socks Should Cover Your Legs
Don't make the mistake of wearing "ankle-length" socks with a suit. While this may seem harmless enough, it's a serious fashion faux-pas that will hurt your overall appearance. So, what's wrong with wearing ankle socks with a suit? The problem is that your legs will likely be exposed when sitting. When you sit down, the bottom of your trousers will rise just enough to reveal your legs -- and that's exactly what you should try to avoid. Instead, choose socks that rise at least halfway up your calf, concealing your legs when sitting and standing.#4) Your Necktie Shouldn't Go Past Your Belt
If there's one accessory you don't want to forget when wearing a suit, it's the necktie. A proper necktie will complete your suit by defining your neck and adding new color. With that said, however, you should position your necktie so it stops right before or at your belt. If your necktie goes past your belt, it's too long and should be replaced or adjusted accordingly.#5) Wear a Black Suit for Strict Formal Attire
If you've done any shopping for a new suit, you're probably well aware of just how many colors in which they come. From black and charcoal to navy and yellow, there are suits in nearly every color you can think of. When dressing for a formal event, however, it's best to stick with an all-black suit. Black suits offer the highest level of formality, making them ideal for such occasions. Of course, you can wear black suits to other events as well. In terms of formality, however, black suits excel in creating a clean, concise appearance that's guaranteed to make you look and feel like a million bucks.
