You are a boy: since you are the best friend, you should help the groom to do everything from morning, including dressing, receiving relatives, welcoming guests, receiving guests, helping to get glasses and bottles when toasting, and helping to see guests off ..... Actually, many things need not be considered, and the relatives, family members and wedding company of the groom will be responsible. You just need to follow the groom step by step to do some auxiliary work.

You are a girl: from morning to the end of the wedding, help the bride make up, change clothes, tidy up things and so on. These will also be helped by the bride's family. You just need to follow her and help her according to her needs!

Don't upstage the bride. All weddings are held for the bride, and the wedding day always belongs to the bride. Even the other protagonist, the groom, is just her foil. Imagine that if you make a splash at someone else's wedding and grab the eye, then you are finished, and you will be the biggest enemy of the bride in this life. Nowadays, weddings are usually held in the central and western regions. The bride wears both western-style wedding dresses and Chinese dresses, so in order not to steal the bride's limelight, there are several colors that must not be worn, that is, white or light beige series and big red. Otherwise, sitting at the banquet and always eating the bride's dirty eyes, those big fish and meat will definitely not be delicious. Of course, if the bride lets you wear it, that's another matter.
