Saint opposed to getting a new suit? (5)
I believe the answer is:
vitus
'saint' is the definition.
(I know that Vitus is a saint)
'opposed to getting a new suit?' is the wordplay.
'opposed to' becomes 'v' (abbreviation for versus).
'getting' says to put letters next to each other.
'a new' is an anagram indicator.
'suit' anagrammed gives 'itus'.
'v'+'itus'='VITUS'
(Other definitions for vitus that I've seen before include "Saint giving name to "dance"" , "Saint (with a pathological dance)" , "Saint whose dance is a disease" .)
