I don't think it's too white. I quite like it for a wedding.
Unless you have a dress code for your wedding, I wouldn't say anything.
It's difficult navigating weddings, some people hate black or white of any discription at their wedding. I think it's best to be upfront about what you expect people to wear, if you don't want any bit of white.
One of my brothers had a black tie wedding, I wore a fab black dress and silver accessories, he and his wife didn't speak to me for 2 years...
You would have hated my wedding, it was all white, everyone wore white.
