A woman's perfume, 'Repose', that dates from 1953 (6,2,7)

'1953' is the definition.
I can't tell whether this defines the answer.

'a woman's perfume repose that dates from' is the wordplay.
I cannot quite see how this works, but
'a' is within the answer.
'woman's' could be 'veres' and 'veres' is present in the answer.
'perfume' could be 'scent' (synonyms) and 'scent' is found within the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
The remaining letters 'fet' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
