I don't have much experience but it's better to start with something and build on that. Lets make it a repository for all things specific to India.

A good perfume usually includes 3 Notes
Top Notes
Perceived immediately upon application of a perfume, top notes consist of small, light molecules that evaporate quickly. They form a person's initial impression of a perfume and thus are very important in the selling of the product. The scents of this note class are usually described as "fresh," "assertive" or "sharp."
Middle Notes
The scent of a perfume that emerges just prior to when the top notes dissipate. The middle note compounds form the "heart" or main body of a perfume and emerge in the middle of the perfume's dispersion process. They serve to mask the often unpleasant initial impression of base notes, which become more pleasant with time. Not surprisingly, the scent of middle note compounds is usually more mellow and "rounded." Scents from this note class appear anywhere from two minutes to one hour after the application of a perfume.
Base Notes
The scent of a perfume that appears close to the departure of the middle notes. The base and middle notes together are the main theme of a perfume. Base notes bring depth and solidity to a perfume. Compounds of this class are often the fixatives used to hold and boost the strength of the lighter top and middle notes. Consisting of large, heavy molecules that evaporate slowly, compounds of this class of scents are typically rich and "deep" and are usually not perceived until 30 minutes after the application of the perfume or during the period of perfume dry-down. Some base notes can still be detectable in excess of twenty-four hours after application, particularly the animalic and musk notes.

How to apply perfume ?
The "pulse points" are locations on the body where the blood vessels are closest to the skin. These spots emanate heat, which can help fragrance to emanate from your skin into the air. (It's the same principle used by essential oil diffusers). Apply your perfume to these points - namely, the inner wrists, the base of the throat, behind ear lobes, behind knees, and the inner elbows. As you wear your perfume throughout the day, it will react with your body heat and continue to emit scent.
Other characteristics of perfume
Longevity - How long the effect lasts. It ranges from few hours to 12+ hours.
Silage (pronounced as See-YahJ) or Projectivity - It's the measure of how further the trail can be noticed.
i didn't know there was this much to discuss in perfumes..
