To fashion (6)
I believe the answer is:
tailor
'to fashion' is the definition.
(I know that tailor is a more specific form of the action fashion)
This is all the clue.
(Other definitions for tailor that I've seen before include "Maker of fitted clothes" , "Fashion" , "Rialto (anag) -- adjust to a specific need" , "Maker of men's suits" , "Cut" .)
