Classy shop refurbished (4)
I believe the answer is:
posh
'classy' is the definition.
(I know that classy can be written as posh)
'shop refurbished' is the wordplay.
'refurbished' indicates anagramming the letters.
'shop' is an anagram of 'POSH'.
(Other definitions for posh that I've seen before include "Luxuriously stylish" , "'Upper class, accent perhaps (4)'" , "Upper-class - Victoria Beckham?" , "Elegant, stylish" , "Shop (anag.)" .)
