Outdated permit to go East (5)

Ross

I believe the answer is:

passe

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

'outdated' is the definition.
(French term meaning out of date or unfashionable)

'permit to go east' is the wordplay.
'permit' becomes 'pass' (passing is a kind of permiting).
'to' says to put letters next to each other.
'go east' becomes 'e' (abbreviation. I am not sure about the 'go' bit.).
'pass'+'e'='PASSE'

Can you help me to learn more?

(Other definitions for passe that I've seen before include "No longer fashionable" , "Outmoded" , "-- -partout" , "dated" , "Out of date" .)
