Apply for example to return outfit (3-2)
I believe the answer is:
get-up
'outfit' is the definition.
(I've seen this before)
'apply for example to return' is the wordplay.
'apply' becomes 'put' (putting is a kind of applying).
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'to return' shows that the letters should be reversed in order.
'put'+'eg'='puteg'
'puteg' in reverse letter order is 'GET-UP'.
(Other definitions for get-up that I've seen before include "Unusual or elaborate costume" , "Style of dress" , "Jump out of bed" , "Outfit" .)
