Koreans think marriage is the most important passage in one's life and a divorce is regarded as a disgrace not only for the couple but also for their families still the divorce rate is growing rapidly these days.
Today's typical wedding ceremony is somewhat different from what it was in old times: first a Western-style ceremony is usually held at a wedding hall or a church with the bride wearing a white dress and the groom wearing a tuxedo, then later in the day the bride and groom have a traditional ceremony at a different room in the venue, in colorful traditional costumes.
Traditional Wedding

In Korea, the marriage between a man and woman represents the joining of two families, rather than the joining of two individuals. As such, the event was often called Taerye (Great Ritual), and people from all over participated.
Steeped in traditional Confucian values, the ceremonies and events surrounding the actual marriage were long and elaborate, from the pairing of the couple to the rituals performed after the ceremony.
In the traditional Korean marriage, the elders of the prospective bride and bridegroom's families decided on all matters regarding the wedding, including the decision of whether or not to marry their son and daughter to each other.

1st Step: Ewheehon

It is a formality that the bridegroom-side and the bride-side discuss about nuptial. In the korean traditional wedding ceremony they value family and customs of a family above everything else. A matchmaker from both families look into family, scholarship, personality and a material harmony of the bridegroom and bride as predicted by a fortuneteller. Then they determine whether they will permit this nuptial or not. In general the Ewheehon is determined when the bridegroom-side sends a proposal letter of marriage and the bride-side sends a reply letter which permits this marriage. In this process only the parents of both families could see the bridegroom and bride.

It is a formality that they send a Sajoo and receive it because an engagement of a young couple has been accomplished. When the bridegroom-side receives an engagement letter or a message from the bride-side, the bridegroom-side sends the Sajoo and a Nabchehmoon which are wrapped in a red cloth wrapper to the bride-side. They estimate a fortune of the bridegroom and bride and the bride-side let the bridegroom know of a wedding date. That is a Youngil. Now a days they change a Nabcheh to Nabpheh.

3rd Step: Napp'ae (Exchanging Valuables)
After they finish the formality to send the Ewheejejang , the bridegroom-side sends an article essential to a marriage ceremony, a marriage letter and the Honsooharm for the bride before they have the wedding day. It is called a Nabpheh. The marriage letter is an important thing and the bride keeps this letter for her whole life as a mean of serving but a single husband. When the bride dies, they bury this marriage letter with her. If the bridegroom-side is not rich, they send just the marriage letter and a Chehdan. The Chehdan are a red and a blue silk for skirt. If the bridegroom is rich, they often send other dress materials. It is called the Bongcheh.
