Continue trying to get those unpacked clothes wearable? (5,2)

I believe the answer is:
press on
'continue' is the definition.
(to press on with something is to continue with it)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for press on that I've seen before include "Continue (regardless)" , "don't stop!" , "Persevere doggedly, quickly" , "Continue (with action)" , "Keep going forward" .)
