Note Elvis-styled trinkets (9)
I believe the answer is:
novelties
'trinkets' is the definition.
('novelty' can be a synonym of 'trinket')
'note elvis-styled' is the wordplay.
'styled' is an anagram indicator.
'note'+'elvis'='noteelvis'
'noteelvis' anagrammed gives 'NOVELTIES'.
(Other definitions for novelties that I've seen before include "Trifles" , "Small toys" , "little presents" , "Small gimmicky knick-knacks" , "Unusual things" .)
