Are we supposed to reapply perfume? I put on two sprays of perfume on my neck at around 7:30 in the mornings, and then I can't seem to smell it anymore. I know that it's because our body adapts and we can't distinguish the smell anymore, but could it also be because of scent faded? Should one ever reapply perfume? And if so, how much later than when first applied? Thanks!
