Old article, quite shabby (7)
I believe the answer is:
antique
'old' is the definition.
('antique' can be similar in meaning to 'old')
'article quite shabby' is the wordplay.
'article' becomes 'an' (indefinite article).
'shabby' is an anagram indicator.
'quite' with letters rearranged gives 'tique'.
'an'+'tique'='ANTIQUE'
(Other definitions for antique that I've seen before include "of great age" , "Long-standing" , "Old relic" , "(Something) valuable because of age and quality" , "Very old and possibly valuable" .)
