伴娘是否一定要未婚，為什麼呢？

外國嘅伴娘未婚叫Maid of Honor，已婚叫Maiden of Honor，應該對新人無衝突。但最好問一問對新人嘅父母介唔介意，唔介意就ok 啦。

唔記得係邊到睇過話係中國傳統習俗入面已經結婚的人做伴娘會對對新人唔好。

In our culture, 伴娘 usually is unmarried female. However, in western countries, bridesmaid/bestman is not necessarily to be unmarry. As long as you are the best friend of the bride, you can be the bridesmaid no matter you are married or divorced.
