It's a common stereotype, often depicted in movies and cartoons, but it's not true.
Just like people of any nationality, French men have a variety of facial hair styles, including:
* No mustache: Many French men don't have mustaches at all.
* Straight mustache: Some men prefer a straight mustache, either thin or thick.
* Handlebar mustache: A classic style, but not limited to French men.
* Other styles: French men can have any mustache style they choose, just like men of any other nationality.
It's important to remember that stereotypes are rarely accurate and can be harmful. Generalizing about entire groups of people based on their nationality or any other characteristic is inaccurate and unfair.
