Whether you collect perfumes for their beautiful bottles or for fragrances, you can lengthen their life with a little consideration. Here is a guide on how to preserve perfumes!

• Keep the perfume away from heat, light, oxygen, dust and dirt. All of them can change its smell character.
• Store perfume in the original bottle. Avoid decanting it into other bottle or spray atomizer.
• Keep the perfume bottle inside its box and store it in a dark closet, dresser drawer, or other covered box.
• Don't keep perfume bottles in refrigerator. Humidity can cause changes in various ingredients of perfume and can destroy the bottle atomizer's mechanism rendering it unusable or making it spray non-stop.
• If possible, always opt for perfume bottles with spray dispensers rather than open bottle. This will prevent excessive oxygen exposure. Sprays also protect perfume liquid from dust and other organic compounds.
• Keep the bottle clean. Wipe it with alcohol occasionally to keep dirt & dust from entering into the bottle.
  

It's true that collectibles are for display but avoid displaying your perfume collection in hallway or some other room where there is enough of sunlight. Store them inside a cupboard for displaying to only limited number of your close friends. That's the price of collecting such a delicate and expensive material!

And yes wearing perfumes occasionally will be wise as the shelf life of any perfume is about five years, which you can prolong a little with proper storage and care. However, whenever, a perfume is spent, you can always collect the bottle, they are exclusive too!
