Layabout concerned with headgear? (5)
I believe the answer is:
beret
'headgear?' is the definition.
(beret is a kind of headgear)
'layabout concerned with' is the wordplay.
I cannot quite understand how this works, but
'concerned with' could be 're' (re can mean regarding, concerning) and 're' is found within the answer.
The remaining letters 'bet' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beret that I've seen before include "French flat hat" , "Frenchman's flat hat" , "Soft peak-less kind of cap" , "cap in France?" , "Soldier's cap" .)
