Imperium is marketed as a unisex fragrance, but it leans masculine. That said, the mix of florals and fruits appeals to men and women, with many women finding the richness and warmth of the scent attractive. The balance of the scent notes makes the cologne versatile and suitable for various preferences and styles. That said, the appeal of a cologne is subjective. A: Imperium has good longevity, lasting anywhere from 6 to 8 hours on the skin. However, individual experience may vary because of body chemistry, application methods and weather. For the longest-lasting profile and strongest sillage, apply the fragrance to the major pulse points of the neck and wrists.
