In need of repair, some girl pinning a dress up (9)

I believe the answer is:

glamorise

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

'in need' is the definition.
I know nothing about this answer so I can't judge whether this works.

'of repair some girl pinning a dress up' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'some' could be 'a' and 'a' is located in the answer.
'girl' could be 'g' and 'g' is present in the answer.
'up' could be 'is' (I've seen this in other clues) and 'is' is present in the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for glamorise that I've seen before include "present as attractive" , "Make to seem attractive (S, not Z)" , "Beautify spuriously" .)
