I’d wear blazer over shirt? Not me! (6)
I believe the answer is:
nudist
'not me' is the definition.
I can't tell whether this defines the answer.
'i'd wear blazer over shirt?' is the wordplay.
'wear' indicates putting letters inside (to wear something is to be covered up by it).
'blazer' becomes 'sun' (I've seen this in other clues).
'over' shows that the letters should be reversed in order.
'shirt?' becomes 't' (as in a T-shirt).
'id' going within 'sun' is 'sidun'.
'sidun' back-to-front is 'nudis'.
'nudis'+'t'='NUDIST'
Can you help me to learn more?
(Other definitions for nudist that I've seen before include "he reveals all" , "Person who discards clothes by choice" , "one leading a bare existence" , "Person who goes around unclothed" , "who exposes everything!" .)
