Why Do Brides Wear White On Their Wedding Day?

As I was planning my wedding I never even considered what color my wedding dress would be. Obviously I was going to wear white. But why? For tradition sake? To showcase purity? To be the center of attention? Because white went perfectly with my winter theme? Actually I wore white because that's just what I've seen other brides do so I never considered anything else.


Are you wearing white on your wedding day? If so, why?
