“Cobranded endorsement”, i.e. the interactive partnership between a brand and a celebrity, seems to be the last frontier for endorsing a brand and increasing brand popularity. Indeed, the collaborations between a celebrity and a brand are increasing in number and growing in importance. Many new products or capsule collections are created and launched after these partnerships. The paper wants to investigate whether this cobranded endorsement has positive effects on brand equity. Findings from an experimental study carried out in the fashion segment reveal that cobranded endorsements foster a better attitude towards the brand and a higher purchase intention.
