debra

I'm a little stuck... Click here to teach me more about this clue!

'woman' is the definition.

'lose two cups?' is the wordplay.
'lose' becomes 'de' (I can't explain this - if you can you should believe this answer much more).
'two cups?' becomes 'bra' (as in the two cups of a bra).
'de'+'bra'='DEBRA'

'to' is the link.
