Gaudy undergarments on husband (5)
I believe the answer is:
brash
'gaudy' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'undergarments on husband' is the wordplay.
'undergarments' becomes 'bras' (bra is a kind of undergarment).
'on' is a charade indicator (letters next to each other).
'husband' becomes 'h'.
'bras'+'h'='BRASH'
Can you help me to learn more?
(Other definitions for brash that I've seen before include "Flashy, crude" , "Cocksure" , "Vulgarly self-assertive, impudent" , "Cocky and tactless" , "Offensively loud" .)
