The production of modern fragrances

The cosmetic industry, in general, goes to great lengths to develop appealing fragrances in their laboratories and testing departments. Perfumes tend to fall into three categories: middle, top and bottom. This is called space technology and is a means used to group differing scents into identifiable categories. In my opinion, they do not always get it right though. Whether this is down to my sensitive hooter, the scent or the person wearing it, I am not altogether sure. All I know is, when I discern some women passing me by who appear to be wealthy, they smell more like they have doused themselves in fly spray rather than some exotic and expensive potion.
