Cute model to go (4)

I believe the answer is:

twee

'cute' is the definition.
(twee can mean cute or pretty)

'model to go' is the wordplay.
'model' becomes 't' (Ford Model T car).
'to go' becomes 'wee' (both can mean to urinate).
't'+'wee'='TWEE'

(Other definitions for twee that I've seen before include "Over-pretty, sentimental" , "Excessively quaint" , "Excessively sweet" , "Affectedly sweet" , "Pretty-pretty" .)

I've seen this clue in the Sydney Morning Herald.
