Beauty is highly subjective and varies greatly across different cultures, personal preferences, and time periods. There isn't a definitive answer to who the "most beautiful woman in the world ever" is because beauty encompasses more than just physical appearance—it also includes personality, character, and influence. Historically, many women have been celebrated for their beauty, such as Cleopatra, Audrey Hepburn, Marilyn Monroe, and others. In modern times, public figures like actresses, models, and influential women are often recognized for their beauty, but opinions differ widely. If you have a particular era, culture, or type of beauty in mind, I can provide examples or discuss notable figures known for their beauty. Would you like that?
