Party rubbish? He gets a woman (8)
I believe the answer is:
dorothea
'woman' is the definition.
'party rubbish? he gets a' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'rubbish?' becomes 'rot' (both can mean nonsense).
'gets' is a charade indicator (letters next to each other).
'do'+'rot'+'he'+'a'='DOROTHEA'
(Other definitions for dorothea that I've seen before include "Girl" , "Mrs Casaubon" , "Woman" , "gift from God" .)
