Below bag belonging to woman (6)
I believe the answer is:
nether
'below' is the definition.
(I've seen this before)
'bag belonging to woman' is the wordplay.
'bag' becomes 'net' (I've seen this in other clues).
'belonging to woman' becomes 'her'.
'net'+'her'='NETHER'
(Other definitions for nether that I've seen before include "North European country" , "Subordinate" , "These garments are for the bottom half" , "Located below" , "Situated below" .)
