Style — very large amount (3)
I believe the answer is:
ton
I believe this is a double definition.
'style' is the first definition.
(term for style or fashion)
'large amount' is the second definition.
(I've seen this in another clue)
'very' acts as a link.
(Other definitions for ton that I've seen before include "2240lbs" , "Heavy weight or 100mph" , "People of fashion" , "Weight - fashion (French)" , "Twenty cwt" .)
