My birthday party was great! One of my friends came to the party in casual clothes. I didn't say anything but she felt a bit disappointed. I was really sorry for her. What would you say if you were in my place? What do you usually wear when you go to birthday parties? Is it important to wear smart clothes when you go  to a birthday party?
