A brand is considered luxury when it is very expensive and when not anyone can simply walk into one of their stores and walk out with one of their products. Their clientele must be very exclusive and limited mostly to those who are financially well-endowed.
In terms of fashion and beauty, some of the top most luxurious brands of all time include Gucci, Chanel, Dior, Louis Vuitton, and Prada. These brands have been known to produce very high-quality products that are in demand all over the world.
