Got a change of clothing (4)
I believe the answer is:
toga
'clothing' is the definition.
(toga is a kind of clothing)
'got a change' is the wordplay.
'change' is an anagram indicator.
'got'+'a'='gota'
'gota' anagrammed gives 'TOGA'.
'of' acts as a link.
(Other definitions for toga that I've seen before include "Got a cloak for an old Roman" , "Roman raiment" , "One-piece Roman wrap" , "Old-style dress" , "Outer garment" .)
