Would love to have your ideas on design of bridal shower cakes?

I would love to have your suggestions on designs for bridal shower cakes for weddings. The color of it should contrast with the violet theme we are opting for the shower party. My budget to spend on it varies from 500 to 700$ including the delivery of it to my place in San Francisco, California. I want some eye catchy designs on it with fresh flowers and vanilla flavored, the one our friend loves to have.
