In the past it was always in the morning which was believed to be best time for a joyful celebration such as wedding ceremony to take place, whereas the afternoon is considered the time for sad ceremonies like cremations. However, with modern lifestyles convenience has become more important so the time doesn’t really matter any more. Generally, 10:00am and 4:00pm are usually considered the best times because guests are invited to have lunch or dinner after the official ceremony is finished.

The wedding preparations start with the sou khor (bride-price negotiation) procession.

The bride-price is usually money and gold, but it can be anything valuable. Traditionally this is asked by the bride's parents as a refund for the breast milk that has been fed to the bride since she was born (literally translated from Lao). How much? depends on the family social status of both sides. Nowadays many parents don't ask for anything so long that their daughter is happy.

When both sides negotiate and agree on the bride-price and all other details then they set the wedding date.

Traditionally, the wedding date has to be on a good day in lunar calendar, so parents of either or both sides usually consult elders or senior ex-monks, who have good knowledge of Lao custom and tradition, before the wedding date is set. One thing most Lao knows is that the wedding is not supposed to take place during the three months khao phansa (Buddhist Lent, late July - late October).

Today this procession has been slightly changed to suit modern lifestyles and sometimes the couple agrees on most of the details (including the bride-price) and they set the date to suit their busy lives. When it comes close to the wedding day, this sou khor procession is organised just for the sake of Lao custom or tradition.

The night before the Laos wedding takes place, an informal ceremony is held at the bride-to-be’s home, and sometimes the groom holds the same ceremony at his place as well. This is call an oun dong (wedding or marriage warming) and it only involves close friends and relatives who come to help with wedding preparations as well as to eat and drink.

The things to prepare include pha khoun (handmade marigold pyramid made of banana leaves), food for the big day and the new couple’s bedroom. In this room tradition demands the bed must be made by the mother of the bride or an older female who has a good family (with a good husband and good children and who is not divorced, or a widow).

On the big day, the bride is dressed with a traditional Lao silk sinh (Lao skirt), and silk blouse, and has her hair tied up in a special way with gold decoration. This ensemble is finished off with a gold necklace, bracelets, earrings and a bell.

The groom also gets dressed up usually with white or cream coloured silk shirt and a traditional silk salong (a pair of baggy pants). Sometimes grooms wear normal pants and suits as some find salongs uncomfortable.

Traditionally, on the wedding day a small baci (also spelt basi) or sou khuan (a spirit enhancing) ceremony is held concurrently in both the bride’s house and the groom’s prior to the formal wedding. Now many omit this custom, especially in urban areas where Lao customs and traditions are fading.

Once the small baci is finished, a convoy of the groom is sent ahead to give the bride-price to the bride’s parents. The bride-price could be gold or money. The convoy usually consists of few older men and women, who could be the groom’s parents and relatives who are good and know a lot about Lao customs and traditions.

The leader of the convoy would politely say something like “we come with horses, buffaloes, cows, a pile of silver and gold to give to you in exchange for our son coming to live with you” or something similar. While this exchange is taking place the groom’s group is formed and waits somewhere nearby.

When the procession is finished, the groom’s group is informed and they begin to walk to the bride’s home, playing musical instruments, singing and dancing along the way. Everybody is laughing, cheering and smiling in the most joyful way. The groom walks under an umbrella carried by his friend. This part of the Laos wedding is supposed to be really fun to join. This procession is called hae keuy.

When they arrive at the bride’s house, the groom and his party are met by the bride's relatives where a silver door and a gold door are set up and closed. These doors are just lines of silver and gold bells stretched across the door way to prevent the groom entering before he is granted permission. The groom will be allowed to go inside only after he drinks with the bride’s relatives and pays them to open the doors and after their customary questions such as: “Where did you come from? What did you come here for? What did you bring with you?” etc. are answered. So… extensive bargaining, questioning and drinking takes place here which is another fun part of the Laos wedding.

The groom doesn’t have to answer the questions because the elder relatives will do all the talking and answering for him. The elders from both sides talk in a customary, polite and friendly way which doesn’t have to be real. All the groom has to do is to drink his way through and give some money to the door attendants. This is like an entry fee but it doesn’t have to be much and the money would already have been prepared for him by his relatives. When he has paid and they are satisfied with the small money gift they will allow him to step through.

However, it’s not finished yet. Before he can enter the house he has to have his feet washed by the bride’s younger sister or the female relative of the bride who is younger than she is. The groom has to give a money gift to the person and then he can enter the house.

The groom is met at the door and led by a female relative of the bride to the pha khoun, where the baci ceremony will be taking place. Once he is settled in, the bride is led to the pha khoun from her room by another elder female relative. She is seated on the left side of the groom with the parents and relatives of both sides sitting nearby. During the seating process the bride’s relatives and friends will give her a slight push to make her to lean on the groom unintentionally, and the other party will try to push the groom the same way. It is believed that the first to touch the other one in this ceremony will have more power over the other party in their married lives.

After everyone is settled in, the baci or sou khuan ceremony begins. This involves the chanting by the master of ceremony (mor phon), the egg feeding (the bride and the groom feed each other an egg) and the tying of white strings on wrists to unite the couple. At the end of the baci, the elder relatives lead the couple to somma (a customary asking for forgiveness and thanking of parents and elder relatives of both parties). This process involves the giving of small money gifts (wrapped inside banana leaves, together with flowers and a pair of candles). During this ceremony, the elders, including the parents and relatives of both parties, give the couple good wishes.

The Laos wedding ceremony ends with the sending of the couple to their room. The elder female relative will lead the groom to the room and the bride follows behind. Traditionally, the couple is supposed to stay in their room until the next morning. However, as the order of this ceremony has changed over time, it now takes place before the party (in the past it was after the party) because the newlyweds have to greet the guests.

After the baci is over, it is time for the party to begin when the guests are invited to eat, drink and dance.

Today, most people split their wedding into two parts, one is a traditional Laos wedding ceremony and the other is a modern Laos wedding party. Some have the traditional Laos wedding ceremony at home in the morning and some do it in the afternoon. Only close friends and relatives are invited to join the baci part. Whether the baci takes place in the morning or afternoon, food and drinks are served to the guests at the end of the ceremony. The party is then held at a hotel or a restaurant in the evening when more guests are invited. This practice is more common among city people.

This Laos wedding ceremony is practised by ethnic Lao and can vary from place to place. Other ethnic groups have their own customs and traditions which are often very different.
