You will be surprised to know, that a perfume lasts differently on different parts of our body. Most of us apply the perfume on our clothes, well thats not where we should apply them.
Ideally start with your neck, shoulder, lower jaw & chest. Follow it up with your wrist, fore arm & inner elbow. Perfume tends to radiate more if you apply at these warm places.
Women, additionally should also apply the perfume just below the mid riff, behind the knee, calves & ankles. By doing so, you will be able to extract the maximum impact out of your fragrance.
