Bluth covers breaking news: vacuous actor reveals masculine habits (8)
I believe the answer is:
menswear
'masculine habits' is the definition.
(habit can mean clothing)
'bluth covers breaking news vacuous actor' is the wordplay.
'bluth' becomes 'me' (where the crossword setter is 'Bluth').
'covers' is an insertion indicator.
'breaking' indicates an anagram.
'vacuous' means to remove the middle letters.
'actor' with its centre removed is 'ar'.
'news' with letters rearranged gives 'ensw'.
'me' enclosing 'ensw' is 'menswe'.
'menswe'+'ar'='MENSWEAR'
'reveals' acts as a link.
(Other definitions for menswear that I've seen before include "Male attire" , "Boxers, for example" , "Clothing for males" , "Male outfits" , "uniform, perhaps" .)
