Circus clown's collection (5)
I believe the answer is:
noses
'circus clown's collection' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for noses that I've seen before include "Beaks, conks" , "Facial features" , "Olfactory organs" , "Hooters" , "Pries" .)
