Showy address accommodating fan base (6)
I believe the answer is:
ornate
'showy' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ornate that I've seen before include "Over-decorated" , "Rococo" , "Flash" , "Richly decorative" , "Highly embellished" .)
