Summarize this article:

You can blend in more easily in a crowd by wearing clothing that is dark in color, such as black, dark gray, and dark blue. Bright colors often make you stand out and announce your presence to others. You may decide to create a uniform of dark clothing that you wear throughout the week, such as dark blue jeans and black sweaters or shirts. You may then wear this dark clothing every day to blend in, no matter where you are. Eye contact is a key part of projecting positive body language that is welcoming to others. You can blend in and avoid interactions with people by averting your gaze so you do not make eye contact. Often, people will take a lack of eye contact as a sign you are not interested in making conversation or in connecting with others. You can also demonstrate closed body language, where you fold your arms over your chest and turn your body away from the person you are interacting with. These actions will likely discourage people from speaking or interacting with you and allow you to blend in more easily in a group. You can also blend in by not speaking up or saying much at all when you are around a group of friends or acquaintances. Staying silent when you are around others will make your presence less known and allow you to be almost invisible. This is not a great way to make friends or connect with others, but it will deflect attention away from you. You may also spend time on your own more than with others or with friends, as you will not have to worry about trying to blend into a group when you are alone. This can be isolating and lonely, but it can at least ensure that you will not stand out or be noticed by others.

Summary:
Wear dark clothing. Avoid eye contact. Keep your thoughts and opinions to yourself.
