General shown in protective garment (7)
I believe the answer is:
overall
I believe this is a double definition.
'general' is the first definition.
('overall' can be similar in meaning to 'general')
'protective garment' is the second definition.
(overall is a kind of protective garment)
'shown in' is the link.
(Other definitions for overall that I've seen before include "In total" , "On the whole - protective garment" , "Taken as a whole" , "Boilersuit" , "protector" .)
