       Weddings are important in every country, and there are different wedding customs in different countries. In western countries the bride's (新娘的) dress—her wedding dress—is very important. Some brides wear a new dress. Some brides wear the dress their mothers or even their grandmothers wore at their weddings.

       Some people believe the bride should wear something old, something new, something borrowed, something blue. She may wear an old ring and will usually have new shoes. She may borrow something to wear from a friend, and the ring on her finger may have a blue jewel in it or some of her clothes may be blue.

       Many married people in western countries wear a ring to show that they are married. They wear the ring on the fourth finger of their left hands.

       At the wedding, as soon as the man and the woman are married, their friends often throw rice or very small pieces of paper over the couple. They believe this will bring them good luck and that they will have many children. The bride often carries flowers, and after the wedding she throws them up in the air. People believe that the woman who catches the flowers is lucky enough. The bride and the groom (新郎), their friends and family then have a party. After that the bride and the groom go on holiday together. This holiday is called "the honeymoon".
