If you are trying to think of something to make your wedding ceremony special and different, try a tradition from another culture. Asian wedding traditions can be beautiful and meaningful. You could borrow from the following.
In Japan, purple is a traditional wedding color. Use this color in flowers. Purple Irises are gorgeous in the spring.
In China, it is traditional for the bride to wear red, the color of good fortune. If you really want to try something different, wear a bright red wedding dress. They also use loud fireworks to scare off evil spirits. This could be a fun ending to an evening, outdoor ceremony.
