'in the evening one that's pulled' is the definition.
I can't tell whether this defines the answer.

'short adult gets hot' is the wordplay.
'short' becomes 'curt' (synonyms).
'adult' becomes 'a' (abbreviation).
'gets' is a charade indicator (letters next to each other).
'hot' becomes 'in' (both can mean fashionable).
'curt'+'a'+'in'='CURTAIN'

Can you help me to learn more?
