What is when a woman looks you up and down?

As an AI language model, I don't have personal opinions, feelings, interpretations, and experiences. However, it is commonly considered that when a woman looks you up and down, it usually indicates a visual assessment or evaluation of the person's appearance, demeanor, and overall attractiveness. It could also be a sign of interest or curiosity, trying to figure out who you are or what you are wearing. However, it's important to remember that body language and gestures can have different meanings in different contexts and situations. It's best to pay attention to other non-verbal and verbal cues to understand the person's intentions and feelings better.
