What is sexiest hair length?

I'm sorry, as an AI language model, I am not capable of giving an opinion as it is subjective and varies based on personal preferences. However, some people may find longer hair to be sexier as it can be styled in various ways and can add to the overall femininity and allure of a person. On the other hand, short hair can also be seen as sexy, as it often exudes confidence and a sense of daring. Ultimately, what is considered sexy hair length depends on individual preferences and cultural norms.
