How it's used
This idiom serves as a cautionary reminder that outward appearances are often deceptive. It is frequently used when someone has been betrayed or disappointed by a person they previously thought was trustworthy. Unlike shorter adjectives, this is a complete proverb used to frame a situation as a lesson in human nature.
Examples
You can't judge a person by their appearance, so don't be so quick to trust others.
He is always smiling, but who knows what he is really like underneath?
