Stoop to embrace small Queen producer (8)
I believe the answer is:
designer
'producer' is the definition.
(I've seen this before)
'stoop to embrace small queen' is the wordplay.
'stoop to' becomes 'deign' (I've seen this in another clue).
'embrace' means one lot of letters goes inside another.
'small' becomes 's' (abbreviation - e.g. clothes size).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'deign' placed around 's' is 'design'.
'design'+'er'='DESIGNER'
(Other definitions for designer that I've seen before include "Style creator" , "inventor" , "Planner; draughtsman" , "Stylist" , "Producer" .)
