The most accurate way to see what you look like to others is to use a mirror. When you look into a mirror, you are seeing a reflection of yourself as others would see you from the front. This gives you a fairly accurate representation of how you appear to others in terms of facial features, expressions, and body posture.
However, keep in mind that a mirror only shows you a two-dimensional reflection of yourself. In reality, you are a three-dimensional being, and people perceive you from different angles. Different lighting conditions and the distance from which others view you can also affect how you appear to them.
If you want a more comprehensive understanding of how you look to others, you can consider taking photographs or videos of yourself from various angles and in different lighting conditions. This can help you gain insights into your appearance from different perspectives and see yourself as others might see you in more dynamic situations.
It's essential to remember that perception of physical appearance is subjective and can vary from person to person. Our self-perception can also be influenced by our emotions and self-esteem. It's important to focus on being comfortable and confident in your own skin rather than seeking external validation or constantly comparing yourself to others.
