What city in the U.S. has the prettiest people?

Could you please elaborate on what criteria you're using to determine which city in the U.S. has the "prettiest" people? Is it based on physical attractiveness, cultural diversity, or a combination of factors? Also, is this a subjective or objective assessment? Finally, could you provide some evidence or examples to support your viewpoint? It's worth noting that beauty is a subjective concept and can vary greatly from person to person.
