When it comes to knowing how to wear perfume, there's a few more interesting facts then just where to spray it or how much to apply. Knowing how to properly wear perfume also includes knowledge of how to give your perfume a longer shelf life! Old perfume or perfume that hasn't been stored properly won't give off a fresh scent and won't last you as long. If possible, keep your perfumes stored in the fridge! If that's not an option, keep them in a cool, dry place out of direct sunlight. Bathrooms are so moist that perfumes don't last long in there!
