I believe the answer is:

brenda

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

'something feminine' is the definition.
I can't judge whether this definition defines the answer.

'she'll finish up in' is the wordplay.
'she'll' becomes 'bra' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'finish up' becomes 'end' (to finish is to come to an end).
'in' is an insertion indicator.
'bra' going around 'end' is 'BRENDA'.

Can you help me to learn more?

(Another definition for brenda that I've seen is " - - Blethyn, actress".)

I've seen this clue in the Evening Standard.
