Clothing hit hard (7)
I believe the answer is:
clobber
This could be a double definition.
'clothing' is the first definition.
(informal UK term for clothing)
'hit hard' is the second definition.
'clobber' can be an answer for 'hit' (I've seen this before). I'm not certain of the 'hard' bit.
Can you help me to learn more?
(Other definitions for clobber that I've seen before include "bash" , "what one barely lacks" , "Kit" , "Hit hard; clothing" , "Lick" .)
