I was asked by a bride to create a cake incorporating flowers and bling a month and a half ago (finally got around to writing a post for it!). The design I came up with combined the two elements together: bling within the flowers. A white cake provided a simple canvas on which bright, bold, fuchsia flowers with rhinestone centres would pop. A thin band of bling at the base of each tier tied the flowers together with the cake.
I didn't want the cake to be overly flashy or blinding but still have that sparkle the bride was looking for. The finished product achieved the look I was striving for - a simple elegance, delivery on the wattage without over-the-top bling =)
