What is when a guy says you look great?

When a guy says “you look great”, it is usually a compliment. It could mean that he finds you attractive and is impressed by your appearance. He may be trying to make you feel good about yourself and build your confidence. It is also possible that he simply noticed a positive change in your appearance and is acknowledging it. In any case, it is a friendly and respectful remark that should be taken in a positive light. However, it is important not to read too much into it and assume that there is romantic interest unless there are other clear signs of attraction.
