A perfumes scent will greatly differ within its surroundings. Your impression of a scent sprayed in a large heavily scented department store can be different than sprayed in your own home. Differences in temperature and humidity can also play a huge part in the smell of the perfume. However the main differences in the olfactory effect of a perfume is the compounds it contains, which will evaporate at relatively different speeds, this will affect all brands of perfume.

The way a perfume is described by the perfumers is by its fragrance composition. Top note, heart note and base note. This explains the way a scent develops and will be completely different in every perfume.

If you are searching for that perfect perfume, don't overdo it by spraying many, many different perfumes all over you as you nose will go "blind" and you will not be able to tell if you like the fragrance or not.

You should only test about four or five different perfumes at any time; you should spray these on an unperfumed part of your body and as far apart from each other as possible. In addition, a perfume will smell different on the individuals skin, what smells good on one person could smell totally different on yourself, this should be taken into consideration before choosing the right perfume.

Perfume is meant for people to enjoy when they are in close quarters with you, not for the people across the other side of the room. Don't apply too much perfume at any one time as this may make your scent appear too strong and you may not achieve that ideal perfumed fragrance.
