Briefs boss employed in the clothing industry (6)
I believe the answer is:
fibres
'boss employed in the clothing industry' is the definition.
I can't tell whether this defines the answer.
'briefs' is the wordplay.
'briefs' anagrams to 'FIBRES'.
Though, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for fibres that I've seen before include "thin strands or threads" , "They may be spun" , "Threadlike structures" , "Threadlike substances" , "Filaments" .)
