The term "brand ambassador" loosely refers to a commodity which covers all types of event staff, varying between trade show hosts, in-store promotional members and street teams. Previously, the job of a brand ambassador was undertaken typically by a celebrity or someone of a well-known presence, who was often paid considerably for their time and effort. Nowadays however, a brand ambassador can be anyone who has knowledge or can identify certain needs a brand is seeking. The fashion industry, however, still solely relies on celebrity clientele in order to remain brand ambassadors. Furthermore, brand ambassadors are considered to be the key salesperson for a product or service on offer. They must remain well-informed when it comes to the brand they are representing, due to their nature of being the go-to person when questions arise from consumers. The brand ambassador's job is to drive results through communication tools either publicly, such as social media, or privately including emails, messaging and further one-to-one channels.
