Star to rage when drunk grabs dress (5,5)

Ross

I believe the answer is:

greta garbo

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

'star to rage when drunk grabs' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'dress' is the wordplay.
I cannot really understand how this works, but
'dress' could be 'garb' (synonyms) and 'garb' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for greta garbo that I've seen before include "See actress" , "Old actress" .)
