According to traditional customs, bridesmaids cannot be married more than three times, and there is no scientific basis for this. Nowadays, people do not take this custom seriously.
1. Traditional customs
For the traditional view, being a bridesmaid can be done three times. The traditional custom is that being a bridesmaid is actually equivalent to sharing one's fate and good fortune with the bride. Therefore, every time one bridesmaid is done, one's fortune will be less. If one is done too many times, it will lead to a thinner fate and make it difficult to meet one's significant other. Therefore, being a bridesmaid can only be done three times at most.
2. Modern perspective
But now everyone's thinking has opened up, and they don't believe this traditional custom to be true. If a friend around them needs to be their bridesmaid when they get married, everyone will think it's a kind of luck and happiness. It doesn't matter how many times they go, they will go.
