The most obvious fact when considering the importance of wearing perfume is the main purpose of the perfume is to keep unpleasant body odours at bay and make sure you smell fresh throughout the day. The best practice for wearing a perfume is to apply it to dry skin. You’ll want to focus it on heated areas on your body, including your chest, neck, lower jaw, wrist, forearm, inner elbow and shoulders. Your body heat helps diffuse the scent and make the scent last longer.
