Most courageous wearing two garments (7)
I believe the answer is:
bravest
'most courageous' is the definition.
('brave' can be a synonym of 'courageous')
'two garments' is the wordplay.
'two garments' means two replacements for 'garment'.
'garment' becomes 'bra' (bra is a kind of garment).
'garment' becomes 'vest' (vest is a type of garment or item of clothing).
'bra'+'vest'='BRAVEST'
'wearing' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bravest that I've seen before include "Most valorous" , "Most valiant" , "Most handsome" , "Most courageous" , "Most heroic" .)
