Upper-class Albion fan he’s turned out (13)
I believe the answer is:
unfashionable
'out' is the definition.
(synonyms)
'upper-class albion fan he's turned' is the wordplay.
'upper-class' becomes 'u' (similar in meaning).
'turned' indicates an anagram.
'albion'+'fan'+'hes'='albionfanhes'
'albionfanhes' is an anagram of 'nfashionable'.
'u'+'nfashionable'='UNFASHIONABLE'
(Other definitions for unfashionable that I've seen before include "Not chic" , "Not popular" .)
