Dismissed one putting on paper clothes (6)
I believe the answer is:
outfit
'clothes' is the definition.
(outfit is a kind of clothes)
'dismissed one putting on paper' is the wordplay.
'dismissed' becomes 'out' (dismissed in cricket).
'one' becomes 'i' (Roman numeral).
'putting on' means one lot of letters goes inside another (some letters wear or 'put on' others).
'paper' becomes 'ft' (Financial Times newspaper).
'i' going inside 'ft' is 'fit'.
'out'+'fit'='OUTFIT'
(Other definitions for outfit that I've seen before include "Costume" , "Set of clothes or equipment" , "Kit, rig-out" , "Organisation or set of clothing" , "Ensemble of clothes" .)
