ooh no. Not good for a wedding- like someone said, it's too vampy.
I always think you need something slightly sweet and English-y for a wedding. It's not about being the most attractive one there, it's about wearing something that you, the flower girls and granny will 1. like and 2. not be offended by. (That's always my rule of thumb).
If you go to a wedding dressed like a vamp people will think you have some kind of axe to grind!
