Doctor's striking costume (3-3)
I believe the answer is:
rig-out
'costume' is the definition.
(I've seen this before)
'doctor's striking' is the wordplay.
'doctor' becomes 'rig' (both can mean to manipulate or tamper with).
'striking' becomes 'out' (striking out is a common phrase).
'rig'+'out'='RIG-OUT'
