Leather women must wear wild-haired (7)
I believe the answer is:
rawhide
'leather' is the definition.
(thesaurus)
'women must wear wild-haired' is the wordplay.
'women' becomes 'w'.
'must wear' means one lot of letters goes inside another.
'wild' indicates anagramming the letters.
'haired' is an anagram of 'rahide'.
'w' going inside 'rahide' is 'RAWHIDE'.
(Other definitions for rawhide that I've seen before include "Stiff untanned leather" , "Leather before tanning" , "Whip" , "Untanned animal skin cut to make whips and ropes" .)
