The bottom tier is 8 6" rounds with a 10" round in the middle. The bottom and 4th tier are draped with fondant, the other tiers are all buttercream. The broaches, monogram & rhinestone ribbon (on top tier) are not edible. I used spray luster dust on all the tiers. The diameter of the bottom tier (6" rounds) was 24", 2nd tier 20", 3rd tier 16", 4th tier 12", 5th tier 10", 6th tier 6".
