I read an article on The Atlantic today that reminded me about how you can literally dress the shy away.
It is an fact is you dress formally you will feel better about yourself and your self esteem grows. People even treat you even with more respect. I have often heard people say they are not comfortable in business attire and I was one of them. The truth was I just had not found the right clothes that fitted me perfectly.
If you find the right clothes you will feel better about yourself, your confidence will go up and people will treat you with more respect.
For further reading you can read the article I mentioned. It is called Wearing a Suit Makes People Think Differently written by Joe Pinsker.
Have a great day!
