Wearing attitude, for example (8)
I believe the answer is:
instance
'example' is the definition.
('instance' can be a synonym of 'example')
'wearing attitude' is the wordplay.
'wearing' becomes 'in' (wear in (and 'in' is fashionable)).
'attitude' becomes 'stance' (stance is a kind of attitude).
'in'+'stance'='INSTANCE'
'for' is the link.
(Other definitions for instance that I've seen before include "Canniest (anag) - occurrence" , "Case or example from ancients" , "Particular example" , "Specimen" , "Cite as an example" .)
