brenda

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

'does she' is the definition.
'Brenda' can be an answer for 'she'. I'm unsure of the 'does' bit.

'finish up in a very abbreviated garment?' is the wordplay.
'finish up' becomes 'end' (to finish is to come to an end).
'in' indicates putting letters inside.
'a very abbreviated garment?' becomes 'bra' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'end' inserted into 'bra' is 'BRENDA'.

Can you help me to learn more?

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