I bought a new hat yesterday.

In my current job, I wear many hats , from project management to customer service.

He wore a cocked hat to the formal event.

He looked stylish in his porkpie hat.

He wore a slouch hat to protect himself from the sun.

The general proudly wore his brass hat during the military parade.

He scored a hat trick in the soccer game.

He wore an opera hat to the theater.

He is always ready to help at the drop of a hat.

Wearing a top hat to a casual party is old hat.
