Simplicity- Wedding cakes are usually very extravagant, but this one is pretty simple. The simplicity is either to accent the other over the top things at the wedding, or maybe the couple wanted a simple wedding all around.
I think the bottom layer should have peach fondant, or instead of the flower at top, a third layer with just one pearl strand. but overall a pretty idea. (Coco Chanel Pearl Cake by Lisa Rochelle of Sweet Grace Cake Design )
