Killer Queen by Katy Perry is a royal fragrance that exudes sophistication and glamour. The aroma opens with notes of wild berry, dark plum, and bergamot, followed by a floral heart of red velvet flower, jasmine, and frangipani. At the base, the scent is grounded by cashmere, praline, and patchouli. It's a feminine and alluring scent that will make you feel like royalty.
