First, look at your identity. Are you a guest invited by the bride or a good sister of the bride? If you are a guest, there is no special requirement for clothing, as long as it looks neat and solemn. If you are the bride's good sister, you should make careful preparations, but don't care too much about facial makeup, because the bride is the protagonist. If you wear clothes, dress yourself up when you get married. Be careful not to wear suits, work clothes and the like, mix and match. You women are good at this. I don't need to say more. If you are not married, you can consider wearing a small black suit with a Yanling shirt inside. A neutral but fashionable dress will also have a good effect.
