Sexual dimorphism can evolve when selection favors the expression of a trait to be different in males and females. 

This situation is called sexually antagonistic selection, because an increase in the trait’s expression benefits one sex but harms the other.

Exaggerated secondary sexual traits are favored by sexual selection because they increase male mating success.
