This shirt matches the color of my suit perfectly.

"Suit" is a type of formal men's attire that consists of a jacket, pants, and sometimes a vest or other accessories. It is typically made of a matching set of fabric and is worn for business or formal occasions.

Here are some other examples of sentences that use "suit" in different contexts:
