Hat for Indiana Jones (6)
I believe the answer is:
fedora
'hat for indiana jones' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for fedora that I've seen before include "Headgear" , "Felt hat dented sideways" , "Cover for head" , "top fashion" , "Felt hat much loved by 1930s gangsters" .)
