If you really think about it, weddings (and all special events) essentially are quite similar: there typically is a ceremony with a reception to follow, where the couple can celebrate their marriage with family and friends.
Yet these events are really SO different in almost every way. No two brides are going to carry the same exact bouquets. No two wedding parties are going to choose to pose in the same exact way for their pictures. No two couples are going to have the same exact ceremony. Every small detail tells your love story. Every decision made for your special days represents who you are as individuals and as a couple.
And I think the idea that your wedding is totally, 100% about your love and your future makes the day even more special.
