Celebrity wearing badly torn accessory (8)
I believe the answer is:
ornament
'accessory' is the definition.
(I've seen this before)
'celebrity wearing badly torn' is the wordplay.
'celebrity' becomes 'name' (I've seen this before).
'wearing' is an insertion indicator.
'badly' indicates an anagram.
'torn' anagrammed gives 'ornt'.
'name' placed within 'ornt' is 'ORNAMENT'.
(Other definitions for ornament that I've seen before include "Turn" , "accessory" , "Trinket - decoration" , "deck" , "trill?" .)
