Wear and tear, it might be (6)
I believe the answer is:
attire
'wear' is the definition.
(attire is a kind of wear)
'tear it might be' is the wordplay.
'might be' indicates anagramming the letters.
'tear'+'it'='tearit'
'tearit' with letters rearranged gives 'ATTIRE'.
'and' acts as a link.
(Other definitions for attire that I've seen before include "Formal clothing" , "Formal clothes" , "Fine/formal clothes" , "'Dress, garb (6)'" , "(To) dress; fine clothes" .)
