What is when someone looks you up and down?

When someone looks you up and down, they are observing and examining your appearance from head to toe. This can be done for various reasons, such as checking someone out, sizing them up, assessing their level of attractiveness or simply observing their style or outfit. This type of visual inspection can often make people feel uncomfortable or self-conscious, especially if the gesture seems to be judgmental or critical. However, it is important to note that this behavior can also be neutral or positive, depending on the context and the intent of the person doing the looking.
