It's important to remember that:
* People from different regions of France may look different.
* France has a large immigrant population.
* People's appearances are unique and diverse.
Instead of trying to define a "French look," it's more interesting and accurate to appreciate the diversity of people in France.
If you are curious about French people's appearances, you could explore photos of famous French people, or look at pictures of everyday life in France. You will see that there is no single "French look," but rather a wide range of appearances reflecting the country's rich history and diverse population.
