Determining France's definitive No. 1 perfume is challenging, as "No. 1" can be interpreted in various ways (e.g., best-selling, most iconic, most prestigious). However, Chanel No. 5 is arguably the most iconic and recognizable French perfume, holding a prominent place in fragrance history and popularity.
While other perfumes may have higher sales figures in certain years or regions, Chanel No. 5's enduring legacy and global recognition make it a strong contender for the unofficial title of France's No. 1 perfume. The brand Chanel itself is often considered the top French perfume brand.
It's also important to note that "best" is subjective and depends on individual preferences. Many other excellent French perfumes exist.
