The media has been doing a lot of coverage on how the clothing that a business person wears affects the outcome of their success. The problem is that if you are acting like you are on a baseball field you won’t have any better success wearing a suite than you would have in a t-shirt and jeans.
According to a great article on BusinessPundit, body language is probably the most important thing you can change for success. Not only that, but you don’t have to change your personality to make the change.
You will build trust in the person you are talking to by simply maintaining eye contact and not looking off or to the side. Even more important is to have a firm, confident handshake. Take control of the situation, ignore self doubt and you will inspire confidence in both yourself and your business.
