Impeccable grooming for public images
From hats to formal dresses, from a formal dress code for the royal children to specific timing for Tiara, the royal family is surrounded by a dozen of rules, obligations, and restrictions. Kate Middleton goes to a salon around three times a week; to the same Salon, she used to go to before marrying into the Royals, which if the commoners choose to go would cost us around $10000 per year.
The royal family members are required to groom themselves in all aspects, including the dress code, makeup, and haircut, and should look well-groomed at all times. This rule does not only apply to the elder ones of the royal family but also to the children, and that is why kids of Kate Middleton and Prince William always follow a specific grooming pattern even for the public images.
