Woman beautiful in dainty clothes (5)
I believe the answer is:
linda
'woman' is the definition.
'beautiful in dainty clothes' is the wordplay.
'clothes' indicates the answer is hidden within the clue (the letters clothe the hidden word).
'LINDA' is hidden in the letters of 'beautiful in dainty'.
(Other definitions for linda that I've seen before include "lady" , "girl" , "-- Gray, 'Dallas' star" , "23 [LOVELACE]" , "Girl's name (I, not Y)" .)
