Why are bride dolls used on wedding cakes?

Bride dolls are used on wedding cakes as a tradition because of the structure of the cake. When anybody looks at wedding cake, they generally see a structure that is wide at the base, but narrow at the peak. This is very philosophical and symbolic of what the groom's life should be like when married; all things in life should be considered less of a priority than his wife, who is usually positioned at the top of the cake.
