As an AI language model, I am not capable of accessing or providing information about future events or specific rankings beyond the current date. Therefore, I cannot provide you with a list of the top 10 fashion documentaries of 2023 as it would depend on numerous variable factors, including the release dates, popularity, and critical reception of the documentaries that are yet to be made. I recommend checking reliable fashion websites, magazines, or online platforms for updated information on fashion documentaries as they are released.
