Super design for bag (5)
I believe the answer is:
purse
'for bag' is the definition.
(synonyms)
'super design' is the wordplay.
'design' indicates anagramming the letters.
'super' with letters rearranged gives 'PURSE'.
(Other definitions for purse that I've seen before include "Small money bag" , "Means < to close" , "Sum of money as a prize - in pouch?" , "Woman's wallet" , "Money - contract" .)
