Garment donned when going for a spin? (7)
I believe the answer is:
topcoat
'garment' is the definition.
(topcoat is a kind of garment)
'donned when going for a spin?' is the wordplay.
I cannot quite understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
'a' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for topcoat that I've seen before include "clothing" , "Heavy winter outer garment" , "It's worn on the outside in winter" , "Ulster?" , "Final layer of paint" .)
