Dress to impress.

If you dress well and put effort into your appearance, people will be more likely to like you, simply because your appearance carries positive connotations.

1. Dress well and put effort into your appearance.
   If you look attractive and distinguished, people will automatically assume that you are a person of intelligence, integrity, and other such positive character traits. Similarly, if you look unkempt and shabby, people will assume you are lazy, etc. People rarely dig below the surface when it comes to making judgments about others, especially when the other person does not look average.
