Creative type's gender is fluid (8)
I believe the answer is:
designer
'creative type's' is the definition.
'gender is fluid' is the wordplay.
'fluid' indicates anagramming the letters.
'gender'+'is'='genderis'
'genderis' anagrammed gives 'DESIGNER'.
(Other definitions for designer that I've seen before include "Planner; draughtsman" , "inventor" , "Resigned to being the creator, of fashion say" , "Theatre set creator" , "Originator" .)
