Creator set out to make inserts for dresses (6)
I believe the answer is:
'inserts for dresses' is the definition.
(pieces of material added to dresses or skirts)
'creator set out' is the wordplay.
'creator' becomes 'god' (the creator can mean God).
'out' indicates an anagram (out can mean wrong or inaccurate).
'set' with letters rearranged gives 'ets'.
'to make' acts as a link.
