Here's what I would say:

 

The last time I attended a wedding was five years ago. A son of my father's friend was getting married. He is also a friend to my brother and to myself because our parents introduced all of us during childhood. The marriage took place on a warm, sunny day in early September. It was perfect weather for a party. At mid-morning my family and I went to the Church for the ceremony. The Church was set out in the open, and flowers and satin ribbons adorned the surroundings. That was the first time I met the bride, and I found her wearing the traditional white wedding dress. The service took about an hour, and after that we all went to a restaurant by car. The place was huge as it had many rooms and also a beautiful garden with plants, trees, and fountains. There was a buffet waiting for the guests. The newlyweds themselves arrived late because they had been taking pictures all around the city, near the sea, or at the castle. They arrived after almost two hours, and then we were able to start the banquet. We ate for almost three hours. There were a lot of different dishes with meat, fish, or vegetables. Each table had a camera available so the guests could take pictures too. At dusk we returned to the garden to eat the wedding cake. Then they gave us sweets and finally we left. It was a long day, but a nice day, and one spent with friends.
