A blue suit is one of the most significant colors to have in your formal clothing closet. It's suited for practically any occasion and goes well with a variety of shirt and tie combinations. A blue suit is perfect if you are looking to make a statement without making a big deal out of it. The color blue has many variations but a deep, intense navy is probably the closest shade to black in terms of how it affects people's perceptions of your appearance. So if you are looking to make a dramatic impression then a blue suit is the way to go. The color also works well for those who want to project an image of authority. If you are a doctor or lawyer for example, then a blue suit will help others respect you more. Finally, a blue suit can be used to signify loyalty. If you are wearing a blue suit, it means that you are married or attached to someone else. This is usually shown by the wedding ring that comes before the pocket square instead of after it. However, if you are trying to send a different message then a blue suit is the wrong choice. In conclusion, a blue suit is a great option if you want to make a good first impression or if you need to project an image of authority.
