A rigged trial? (5,9)

I believe the answer is:

dress rehearsal

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

'a rigged trial?' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'rigged trial?' is the wordplay.
'rigged' becomes 'dress' (I can't explain this - if you can you should believe this answer much more).
'trial?' becomes 'rehearsal' (I've seen this in another clue).
'dress'+'rehearsal'='DRESS REHEARSAL'

Can you help me to learn more?

(Other definitions for dress rehearsal that I've seen before include "last practice" , "Strip show doesn't need such" , "trial run" , "Final play run-through" , "last chance to get things right" .)

I've seen this clue in The Times.
