When it comes to weddings, there are many "unspoken rules" that society has in place that everyone follows. Many of these rules have to do with what to wear, what kind of gift to give, and who to bring or not bring along with you.
One of the biggest "wedding rules" for people is that women should not wear white, because white is usually saved for the bride. However, sometimes, things can get rather messy when it comes to attire.
