Sock threads (7)
I believe the answer is:
clobber
I believe this is a double definition.
'sock' is the first definition.
(thesaurus)
'threads' is the second definition.
(both can refer to one's clothing)
(Other definitions for clobber that I've seen before include "Flog" , "duds" , "Hit hard; clothing" , "bash" , "Tackle" .)
