Why doesn't my perfume stay on?

Why the heck won’t my perfume stay on or last longer? I recently bought Taylor Swift’s “Wonderstruck Enchanted” and I really love the smell. I put it on today and literally 3 hours later I could not even smell it. I even sprayed it on me a few times. How can I make perfume last longer…. or does it really depend on the perfume itself? Help?! And does putting lotion on your skin before actually help the staying power?
