Old coat I replaced with articles from abroad (7)
I believe the answer is:
exotica
'articles from abroad' is the definition.
(I've seen this before)
'old coat i replaced' is the wordplay.
'old' becomes 'ex'.
'replaced' indicates an anagram.
'coat'+'i'='coati'
'coati' is an anagram of 'otica'.
'ex'+'otica'='EXOTICA'
'with' acts as a link.
(Other definitions for exotica that I've seen before include "Unusual or foreign items" , "curious collection" , "Glamorous things from abroad" , "Unusual articles" , "Items from distant lands" .)
