Great purse design (5)
I believe the answer is:
super
'great' is the definition.
(both can mean excellent)
'purse design' is the wordplay.
'design' indicates an anagram.
'purse' is an anagram of 'SUPER'.
(Other definitions for super that I've seen before include "Marvellous, terrific" , "Prefix meaning over or extremely" , "Terrific, ace" , "of high quality" , "senior cop" .)
