After conducting a comprehensive literature study and crafting hypothesis, some useful data were obtained from the questioners distributed to 157 respondents who had purchased or are using a number of branded or designer bags (including Hermes, Chanel, and Louis Vouitton) in Jakarta, with a snowball sampling and convenience sampling approaches. This followed by an analysis of the data with Structural Equation Modeling (SEM). The research has provided us with an interesting observation whereby brand innovativeness does not have a direct influence on the brand luxury, and on the other hand brand leadership offers positive influence on the brand luxury. Furthermore, brand luxury, brand value, and brand user-imagery fit, all have positive influence on the willingness to pay a premium. And brand value is perceived as the one that has the biggest influence on the willingness to pay a premium. Therefore, to create a brand luxury, one must start by putting a lot of efforts in developing a brand leadership, whether one particular brand has already become a leading brand; an adaptive brand with the ever-changing era; or having a forward long-term vision. By being a brand luxury does not necessary mean that consumers will be willing to pay for a premium. There must be a strong brand value on the basis that they are part of those users of the luxury fashion brand. In shaping the luxury brand and the willingness to pay a premium, companies should consider to “the Brand Luxury Model” in this research.]
