Need opinions on dressing my flowergirl?

So, I'm getting married in less than 7 weeks and still having trouble with my flower girl. My wedding gown is champagne, my bridesmaids are wearing black dresses and carrying champagne roses, the groom is wearing a black tux with a white shirt and champagne vest with a champagne tie. The groomsmen are the same but their vests are black. My pageboy will wear black pants and a white shirt with a black vest. Now...my flower girl will be holding flowers. Her bouquet is the mini verson of mine. I am not sure if I should put her in a gold dress, or a white dress with a black sash. I' leaning towards the white at the moment because of the boys white shirts but what do you guys think?
