answer:It would be helpful to have an idea of what you had worn to the meeting, so we could see exactly what it was about that outfit that gave that impression. There are tons of ways to dress one’s age depending on a person’s individual appearance, style, etc., so it’s not really possible to determine exactly what every 23-year-old should wear. Could you take a picture of yourself in the outfit, or if you’re not comfortable showing your face, lay out the outfit and take a picture of that? And really, it may not be what you wore at all, you may just have a very young look. Do people frequently think that you are younger than you are?
