Clothes tear: it’s awful! (6)
I believe the answer is:
attire
'clothes' is the definition.
(attire is clothing)
'tear it's awful' is the wordplay.
'awful' is an anagram indicator.
'tear'+'it'='tearit'
'tearit' is an anagram of 'ATTIRE'.
(Other definitions for attire that I've seen before include "Formal dress or costume" , "Formal clothing" , "I treat badly the dress." , "Garments" , "Clothes worn" .)
