ornate

I'm a little stuck... Click here to teach me more about this clue!

'decorated sumptuously' is the definition.
'ornate' can be an answer for 'decorated' (I've seen this before). I'm not certain of the 'sumptuously' bit.

'gold awfully neat' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'awfully' indicates anagramming the letters.
'neat' anagrammed gives 'nate'.
'or'+'nate'='ORNATE'

'in' is the link.

Can you help me to learn more?

(Other definitions for ornate that I've seen before include "Richly or elaborately decorated" , "Elaborately decorated, perhaps overdone" , "Detailed" , "Baroque" , "Are not (anag.)" .)
