Bowler perhaps in with a tweak (3)
I believe the answer is:
hat
'bowler' is the definition.
(bowler is a type of hat)
'in with a tweak' is the wordplay.
'in' says the answer is hidden in the clue.
'HAT' can be found hidden inside 'with a tweak'.
'perhaps' is the link.
(Other definitions for hat that I've seen before include "Cap" , "One to cover head" , "Head-covering" , "Eg, derby" , "Lid" .)
