Rome bride disposed to dress up (9)
I believe the answer is:
embroider
'dress up' is the definition.
(embroider can mean to embellish)
'rome bride disposed' is the wordplay.
'disposed' indicates an anagram.
'rome'+'bride'='romebride'
'romebride' anagrammed gives 'EMBROIDER'.
'to' acts as a link.
(Other definitions for embroider that I've seen before include "Sew; embellish" , "Elaborately sew" , "Exaggerate" , "Dress up" , "Add (fictitious) detail to" .)
