Judy's flower arrangement? (7)
I believe the answer is:
garland
I believe this is a double definition.
'judy's' is the first definition.
(actress Judy Garland)
'flower arrangement?' is the second definition.
(I know that garland is a type of floral arrangement)
(Other definitions for garland that I've seen before include "Circle of flowers" , "one who played Dorothy" , "Judy - - , legendary singer" , "Wreath - for Judy?" , "Decorative wreath" .)
