European royal figures, such as Princess Diana and Princess Leonor, continue to influence fashion trends and consumer behavior. Princess Diana was noted for breaking protocol by eschewing gloves to foster human connection, notably when she shook hands with an AIDS patient in 1987. Princess Leonor has created the ‘Leonor effect,’ where her use of accessible brands like Zara and Mango leads to rapid sell-outs among consumers.

Beyond fashion, royal presentation is tied to institutional protocol. While Leonor has established a trendsetting style, she has not yet worn a tiara. Protocol experts note that the use of such jewelry is a strategic decision by the Spanish Royal House rather than a matter of age. The debut of a tiara would serve as a symbol of her definitive entry into visible institutional roles and duties.
