Saint taken aback after god provides clothing (5)
I believe the answer is:
pants
'clothing' is the definition.
(pants is a kind of clothing)
'saint taken aback after god' is the wordplay.
'saint' becomes 'st' (abbreviation).
'taken aback' says the letters should be written in reverse.
'after' means one lot of letters go next to another.
'god' becomes 'pan' (Pan is a Greek god).
'st' backwards is 'ts'.
'ts' put after 'pan' is 'PANTS'.
'provides' acts as a link.
(Other definitions for pants that I've seen before include "boxers?" , "Useless - underwear" , "Useless (slang) - gasps" , "Briefs" , "Puffs, gasps" .)
