Woman in native raiment (4)
I believe the answer is:
vera
'woman' is the definition.
(a woman's name)
'in native raiment' is the wordplay.
'in' indicates the answer is hidden within the clue.
'VERA' is hidden within 'native raiment'.
(Other definitions for vera that I've seen before include "A girl to rave about" , "__ Lynn, the forces' sweetheart" , "Woman's name" , "and 15: Singing Dame" , "Duckworth, Lynn" .)
