Gather this girl's not real cowgirl material? (8)
I believe the answer is:
pleather
'real cowgirl material?' is the definition.
'pleather' can be an answer for 'material?' (type of imitation leather). I am unsure of the 'real cowgirl' bit.
'gather this girl's' is the wordplay.
'gather' becomes 'pleat' (to gather or fold into pleats).
'this girl' becomes 'her' ('her' refers to a girl or woman).
'pleat'+'her'='PLEATHER'
'not' is the link.
Can you help me to learn more?
(Another definition for pleather that I've seen is " Fabric".)
