Most daring underwear for both sexes (7)

I believe the answer is:

bravest

I'm a little stuck... Click here to teach me more about this clue!

'most daring' is the definition.
(I've seen this before)

'underwear for both sexes' is the wordplay.
'underwear' becomes 'bra' (bra is a type of undergarment).
'for both sexes' becomes 'vest' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bra'+'vest'='BRAVEST'

Can you help me to learn more?

(Other definitions for bravest that I've seen before include "Most courageous" , "Most valiant" , "Most daring" , "Most handsome" , "Most heroic" .)
