'decorated' is the definition.
Although both the answer and definition are past participle verbs, I cannot understand how they can define each other.

'revolutionary enters in red pants' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'enters' is an insertion indicator.
'pants' indicates an anagram (UK informal term for 'nonsense' or 'rubbish').
'in'+'red'='inred'
'inred' anagrammed gives 'enrid'.
'che' placed into 'enrid' is 'ENRICHED'.
