It means that a person's appearance, particularly their clothing, can significantly influence how they are perceived by others. It implies that:
* First impressions matter: People often judge others based on their outward appearance, including their clothing.
* Clothing can convey status and power: Certain types of clothing can be associated with wealth, success, or authority.
* Appearance can affect self-confidence: Feeling well-dressed can boost a person's confidence and make them feel more successful.
However, it's important to note that the saying can be somewhat misleading:
* It's not always true: While clothing can play a role in how others perceive us, it's not the only factor. Personality, behavior, and achievements matter just as much.
* It can be superficial: Judging people solely based on their clothes can be unfair and inaccurate.
Ultimately, the saying serves as a reminder that appearance can have a powerful impact, but it shouldn't be the only factor in how we judge others.
