Like tall wedding cakes (6)
I believe the answer is:
tiered
'like tall wedding cakes' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tiered that I've seen before include "In ranks" , "Cunstructed in layers" , "Like some wedding cakes" , "Constructed in layers, like wedding cake" , "Arranged in rows" .)
