Fake leather a guy had worn with Eton jacket (9)

'fake leather' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'a guy had worn with eton jacket' is the wordplay.
'worn with' indicates anagramming the letters (worn can mean damaged).
'jacket' says to hollow out the word (remove centre letters) (the letters worn by the word as a 'jacket' are use).
'eton' with its centre taken out is 'en'.
'a'+'guy'+'had'='aguyhad'
'aguyhad' mixed up with 'en' gives 'NAUGAHYDE'.

Can you help me to learn more?
