Killer Queen’s Royal Revolution from Katy Perry resists the bonds of courtly etiquette, it breaks free of the cage and goes into battle. Killer Queen’s Royal Revolution proves itself to be fearless, brave and beautiful, but at the same time powerful, dignified yet still provocative. The flaçon also possesses these qualities. With the power, strength and beauty of a royal sapphire, it positively hypnotises the viewer with its endless facettes and brilliant shades of royal blue. The cap is evocative of a suit of armour in a shade of revolver grey. The coat of arms stands for the courage and bravery of its wearer.
