As an AI language model, I cannot provide real-time information or predict the future. At the moment, I can only provide information up until 2021. Therefore, I cannot provide a list of the top 10 best-dressed artists in 2023. Fashion trends and opinions on who is considered well-dressed can also vary greatly among individuals. It is best to refer to current articles, fashion magazines, or style experts for the most up-to-date information on the best-dressed artists.
