In taking the dog out, she doesn't wrap up warm (3-2)
I believe the answer is:
pin-up
'she doesn't wrap up warm' is the definition.
I can't tell whether this definition defines the answer.
'in taking the dog' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
'dog' could be 'pup' (I have seen 'Young dog ' mean 'pup' so perhaps 'dog' could also mean 'pup') and 'pup' is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'out' acts as a link.
Can you help me to learn more?
(Other definitions for pin-up that I've seen before include "picture of heart-throb?" , "Photographer's model" , "Poster of an attractive person" , "(Picture of) sexually attractive person" , "Sexy model" .)
