Ragged clothes, the lot — check fabric (10)
I believe the answer is:
'check fabric' is the definition.
'tattersall' can be an answer for 'fabric' (I've seen this before). I'm not certain of the 'check' bit.
'ragged clothes the lot' is the wordplay.
'ragged clothes' becomes 'tatters' (I've seen this in another clue).
'the lot' becomes 'all' (I've seen this before).
Can you help me to learn more?
(Another definition for tattersall that I've seen is " fabric".)
