Perfume is a very personal choice. While for some women selecting a scent is all about the newest trend or having a variety of bottles in her wardrobe, one special scent is the choice made by others, a scent that becomes their own, which their friends know, which their boyfriend remembers, and which they choose without even thinking about it. Research done in psychology indicates that there is a link between scent and such phenomena as memory and emotions. A specific scent might remind of someone's period in life, of some particular relation, place, and maybe even self-image. However, wearing one special scent does not necessarily mean that all women, wearing this particular perfume, reveal the same personality trait. Research on the connection between perfume choice and personality reveals quite a weak one. But the science of smell offers clues about why a familiar fragrance can become deeply meaningful - and why some people may find it difficult to let go of a scent they have worn for years.
