This is your lucky day because my job used to be to work on stealth equipment and to do that I had to understand its underlying concepts in order to better understand how to fix the systems responsible for providing stealth.
First to achieve stealth you need to take a look around and observe your surroundings. In your case you will want to ask questions like, how do the people I want to be seen as; look, move, sound, act, react, dress, talk, what accent do they have, what attitudes do they show, and anything else that you can think of to describe them.
Next you will need to ask the same questions of yourself and when you have the answers you need to compare and contrast the results. Once this is done you need to make a plan or lay out a course of action that will get you from where you are now to where you want to be and once that is done you need to methodically set out to achieve each and everything in your plan.
