Chasubles, perhaps for 100 primates (5)
I believe the answer is:
capes
'chasubles perhaps' is the definition.
(chasuble is a type of religious ceremonial robe)
'100 primates' is the wordplay.
'100' becomes 'c' ('C' can be a synonym of '100').
'primates' becomes 'apes' (ape is a kind of primate).
'c'+'apes'='CAPES'
'for' is the link.
(Other definitions for capes that I've seen before include "Sleeveless cloaks - promontories" , "Short cloaks" , "may be worn" , "Cloaks or headlands" , "Space for cloaks" .)
