Meaning:

People use this proverb to say people tend to be attracted to those who are not like them. People feel those who have different talents, personality, appearance, etc. are attractive to them.

This proverb expresses the idea opposite to the idea of "Birds of a feather flock together."

Example:

A: It looks your mom and dad don't have anything in common. Your mom is plump and outgoing, but your dad is skinny and shy, and loves being alone. He likes math and philosophy, but she likes music and sports.
B: I know that, but they love each other and get along very well. Some people say, "Birds of a feather flock together," but others say, "Opposites attract." That's their case.
