Clothing with split zip (3-2-3-2)
I believe the answer is:
get-up-and-go
'zip' is the definition.
(I've seen this before)
'clothing with split' is the wordplay.
'clothing' becomes 'getup' (getup is a kind of clothing).
'with' becomes 'and'.
'split' becomes 'go' (split can mean to run away or leave).
'getup'+'and'+'go'='GET-UP-AND-GO'
(Other definitions for get-up-and-go that I've seen before include "'pizazz'" , "Vim" .)
