Zip in bizarre costume with split (3-2-3-2)
I believe the answer is:
get-up-and-go
'zip' is the definition.
(I've seen this before)
'bizarre costume with split' is the wordplay.
I cannot quite see how this works, but
'costume' could be 'getup' (a particular outfit or style of dress) and 'getup' is found within the answer.
'with' could be 'and' and 'and' is found within the answer.
'split' could be 'go' (split can mean to run away or leave) and 'go' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for get-up-and-go that I've seen before include "Vim" , "'pizazz'" .)
