The Spanish tie design is exclusive (5)
I believe the answer is:
elite
'exclusive' is the definition.
(I've seen this in another clue)
'the spanish tie design' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'design' indicates an anagram.
'tie' is an anagram of 'ite'.
'el'+'ite'='ELITE'
'is' acts as a link.
(Other definitions for elite that I've seen before include "Privileged or posh group" , "Group considered to have superior status" , "Best, privileged, group" , "Top group f" , "Selected as the best" .)
