Super design for bag (5)
I believe the answer is:
purse
'bag' is the definition.
(purse is a kind of bag)
'super design' is the wordplay.
'design' is an anagram indicator.
'super' anagrammed gives 'PURSE'.
'for' is the link.
(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" .)
