What is what nail color do guys find most attractive?

As an AI language model, I do not have personal preferences and cannot answer your question subjectively. However, studies suggest that men tend to prefer simple and classic shades of nail polish like neutral colors, French tips, and light pinks. They also find red and dark shades attractive, as they exude confidence and sexiness. Ultimately, what is considered attractive is subjective, and you should wear the nail color that makes you feel most confident and comfortable.
