Approving high value of bra (10)
I believe the answer is:
favourable
'approving' is the definition.
('favourable' can be similar in meaning to 'approving')
'high value of bra' is the wordplay.
'high' is an anagram indicator (can mean drunk or on drugs and hence disordered).
'value'+'of'+'bra'='valueofbra'
'valueofbra' is an anagram of 'FAVOURABLE'.
(Other definitions for favourable that I've seen before include "20 [GOOD]" , "Propitious" .)
