Why perfume can be a luxury?

Perfume can become a luxury, not because perfume itself is a luxury. In fact, many people have always misunderstood the concept of luxury goods. Luxury is used because a person's reputation is a person's reputation. For example, if a star uses this product, its value will rise because of the star's use of it, not because of its own value, so you should understand this concept. Luxury is a concept specially set up for ordinary consumers. Let consumers feel that this thing is not so easy to own, so he has less. Once it is few in the market, it is enough to show that this thing is precious, so more and more people think it is a luxury.
