Approve of American fashion (4)

Ross

I believe the answer is:

okay

I'm a little stuck... Click here to teach me more about this clue!

'approve' is the definition.
(I know that approve can be written as okay)

'of american fashion' is the wordplay.
'of' becomes 'o''.
'american fashion' becomes 'kay' (I can't explain this - if you can you should believe this answer much more).
'o'+'kay'='OKAY'

Can you help me to learn more?

(Other definitions for okay that I've seen before include "Alright" , "Permissible (colloq.)" , "Give approval to" , "Informally, all right" , "Authorise" .)

I've seen this clue in The Globe and Mail.
