Actually, for Chinese, a red wedding dress is a tradition symbolizing love and joy.
I say, whatever floats the bride's boat. I don't care if she chooses to wear a duck outfit, if that's how she gets her jolies.
The white wedding dress was actually made popular by queen Elizabeth who chose to wear a white wedding dress, representing chastity, instead of the traditional royal color of silver. Prior to around 1840 brides would just wear their best dress to get married.
