Query: Dissapointed- over time?

Alright so I bought this a perfume a year and a half ago, I LOVED it at first. I used almost a whole bottle! Then I bought another one and switched up my pefume for a while. I went back to the old bottle and sprayed it and it smelled really funky, I don't know why but both of them smell funny after they sit for a while-they don't smell like the bottles in the store. It's like it goes bad after a while? So wtf?
