Help 2nd wedding?

Clara

So I just got married in August but it wasn't the wedding I wanted my sister in law wants to throw me the perfect wedding and I agreed. But I don't know what colors I want for a Christmas Wedding ceremony. My name is Belle and I adore reading and constantly have a book in my hand or I'm singing so it will be the Beauty and the Beast themed princess wedding. I know yellow. And the flowers will be roses but I need another color and advice on how I should do this. I'm new to all this wedding stuff so super confused.
