10. Steer Clear of Foreign Commercial Brands in Public

Motive: To support British businesses without coming across as biased or endorsing
Exception: In the case that the company and the Royals have a major relationship or event
When it comes to maintaining royal etiquette, discretion is key, and overt associations with global commercial brands are strictly forbidden. This unwritten rule guarantees the Royal Family’s neutrality and dignity by keeping them above the tangle of sponsorships and commercial interests.

Exhibiting corporate logos or aggressively endorsing commercial goods might potentially detract from their royal responsibilities and inadvertently provide an endorsement, something that the monarchy has never done before. Their tactfulness does not imply that they avoid using foreign goods; rather, it is the public promotion that they steer clear of. Therefore, even if you could see a royal wearing something by a well-known designer, don’t count on them to become the brand’s face very soon.
