Tailor loves tie in box (10)
I believe the answer is:
television
'box' is the definition.
(the box can informally mean the television)
'tailor loves tie in' is the wordplay.
'tailor' indicates an anagram (letters tailored or designed).
'loves'+'tie'+'in'='lovestiein'
'lovestiein' anagrammed gives 'TELEVISION'.
(Other definitions for television that I've seen before include "Tube" , "Gogglebox" , "box set" .)
