Providing a good first impression to others is very important to start a new relationship. Especially when you are doing a business and meeting lots of people, it's important to deliver yourself at a blink of an eye. In order to do so, you need to be very considerable about what you wear depending on situation and how you'd make gestures as you speak.

Hello, Paul!
