Money namely consumes Queen supporter (9)
I believe the answer is:
brassiere
'supporter' is the definition.
(a bra gives support to breasts)
'money namely consumes queen' is the wordplay.
'money' becomes 'brass' (brass can informally mean money).
'namely' becomes 'ie' (short for 'id est', 'that is' in Latin).
'consumes' indicates putting letters inside.
'queen' becomes 'ER' (Queen Elizabeth).
'ie' placed around 'er' is 'iere'.
'brass'+'iere'='BRASSIERE'
(Other definitions for brassiere that I've seen before include "Female undergarment supporter" , "support" , "garment" .)
