Clothing range with buckles (9)
I believe the answer is:
nightwear
'clothing' is the definition.
(I know that nightwear is a type of clothing)
'range with buckles' is the wordplay.
'buckles' indicates anagramming the letters.
'range'+'with'='rangewith'
'rangewith' is an anagram of 'NIGHTWEAR'.
(Other definitions for nightwear that I've seen before include "habit of one retiring" , "Bed clothing (W, not G)" , "negligee, perhaps" , "evening dress" , "Pyjamas, for example" .)
