Embellished or awfully neat (6)
I believe the answer is:
ornate
'embellished' is the definition.
('ornate' can be a synonym of 'embellished')
'or awfully neat' is the wordplay.
'awfully' is an anagram indicator.
'neat' is an anagram of 'nate'.
'or'+'nate'='ORNATE'
(Other definitions for ornate that I've seen before include "Much-decorated" , "Excessively decorated" , "Elaborate, flowery" , "(Of literary style) complex and with unusual words" , "Detailed" .)
