Scarlett O'Hara's maid (6)
I believe the answer is:
prissy
'scarlett o'hara's maid' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for prissy that I've seen before include "Exaggeratedly proper" , "Overly prim and proper" , "Fussily respectable" , "Strait-laced" , "Prudishly fussy" .)
