It depends on whether your wedding is Chinese or western. If you are from China, red is festive, and warm flowers are added to make a good start. /If it is Western-style, the white wedding dress with white flowers is pure and elegant, and absolutely no one will find fault. But if you don't like the combination of Chinese and western things, it's best not to wear white when toasting. It is ok to take wedding photos, but in the eyes of China people, white is only used to make white things, and you are entertaining guests.
Talk it over with your husband. Don't let it disturb everyone.
I wish you a happy wedding.
