Woman put on new uniform (4)
I believe the answer is:
even
'uniform' is the definition.
(I've seen this before)
'woman put on new' is the wordplay.
'woman' becomes 'eve' (Eve is an example).
'put on' is a charade indicator (letters next to each other).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'eve'+'n'='EVEN'
(Other definitions for even that I've seen before include "Not odd; flat" , "Short joke" , "Late in the day" , "Commensurate" , "Still - quits" .)
