Answers:

The key differentiator is concentration of aromatic compounds in a solvent, which is typically ethanol or a mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The concentration by percent/volume of perfume oil is as follows:

• Perfume extract : 15-40% ( typical 20%) aromatic compounds
• Eau de Parfum (EdP), Parfum de Toilette (PdT): 10-20% (typical ~15%) aromatic compounds. Sometimes listed as "eau de perfume" or "millésime". Perfumes come in this class
  
• Eau de Toilette (EdT): 5-15% (typical ~10%) aromatic compounds. Deodorants fall in this category
  
• Eau de Cologne (EdC): Chypre citrus type perfumes with 3-8% (typical ~5%) aromatic compounds.  Deodorants and body spray fall  in this category
  
• Splash and After shave: 1-3% aromatic compounds
• Perfumes are used sparingly behind the ears and on wrists and at the neck possibly because there is a pulse felt here and with the belief that it would evapourate better and with the mild throbbing.
  
• Deodorants/ eau de colognes/ eau de toilettes are used to mask body odour and are used in arm pits and between legs/thighs were sweating occurs and also in other parts of the body since it is less concentrated and therefore less expensive.
• Shave lotions also have antiseptic properties and are used after shaving and after the bath on the cheek and on the shaved surface
• Using perfume on hankies and clothes should be carefully done to ensure that the cloth does not stain. People who are allergic to perfumes use it on clothes.
  
• Attar is always used on clothes and the perfume remains for a long time. It is higly concentrated. It is popular in the desert regions where water is scarce and is the only solution for body odour.
• Wearing cotton vests helps prevent body odour from reaching clothes and suits. 
• Talcum powder is supposed to prevent perspiration and protect the skin from bacteria that breeds with sweaty skin. Nycil and medicinal powders specifically are summertime powders.

There is also a lovely movie called "Perfume"  directed by Tom Tykwer,where perfume is used as a metaphor and used brilliantly, may I add. Definitely worth watching.:)
