Equipment incluing large garment (4)
I believe the answer is:
Here is my best explanation:
'garment' is the definition.
(kilt is a kind of garment)
'equipment incluing large' is the wordplay.
I cannot quite see how this works, but
'large' could be 'l' and 'l' is found within the answer.
'equipment' could be 'kit' (kit is a kind of equipment) and 'kit' is found in the leftover letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
