In celebration of Lilibet's third birthday, see the color trend that all the royals have adopted to f&ecirc;te their children's birthdays.&nbsp;

Over the past weekend, <a href="https://www.lofficielusa.com/pop-culture/prince-harry-meghan-markle-future-travel-plans" target="_blank" rel="noopener">Prince Harry</a> and Meghan Markle celebrated their youngest daughter, Lilibet Diana, with an intimate, friends and family-only third birthday party. The affair took place outdoors at the family's Montecito home, where guests gathered for an afternoon picnic.&nbsp;
As news of <a href="https://www.lofficielusa.com/pop-culture/meghan-markle-prince-harry-share-family-christmas-card-2021-first-photo-baby-lilibet" target="_blank" rel="noopener">Lilibet's</a> third birthday party emerged, the young princess' first royal baby portrait&mdash;and the only solitary photo officially released by the family to date&mdash;has circulated around the Internet, prompting fans to notice the similarities in appearance she bears to her father Prince Harry, and the striking blue dress she sported.&nbsp;
As it turns out, Lili, as her parents call her, is not the only royal child of the latest generation of monarchs who have sported a light baby blue hue in a first royal baby portrait. Lilibet's brother, Archie, wore the lightest of blue onesies in a sweet shot with his mother, <a href="https://www.lofficielusa.com/fashion/meghan-markle-2024-nigeria-tour-looks-prince-harry" target="_blank" rel="noopener">Meghan Markle</a>, while her cousins&mdash;Princess Charlotte, Prince Louis, and Prince George&mdash;also wore the pastel tone in their respective royal baby portraits.&nbsp;
In particular, fans drew a comparison between the royal portraits of Princess Lilibet and <a href="https://www.lofficielusa.com/pop-culture/princess-charlotte-twinning-kate-middleton-diana-9th-birthday-photo" target="_blank" rel="noopener">Princess Charlotte</a>, who both donned timelessly stylish baby blue dresses and small bows in their hair.
While there are countless fashion rules and codes that must be followed for adult members of the royal family&mdash;ranging from detailed hem length requirements to off-limits <a href="https://www.lofficielusa.com/beauty/nail-trends-for-the-summer" target="_blank" rel="noopener">nail</a> polish colors&mdash;the guidelines for royal baby fashion are decidedly more relaxed. The only true rules for royal children detail that young boys must wear shorts, rather than trousers, and little girls are typically expected to wear dresses.&nbsp;
Given that each and every child of the youngest generation of <a href="https://www.lofficielusa.com/fashion/royal-dress-code-rules-queen-elizabeth-kate-middleton" target="_blank" rel="noopener">royals</a> has sported the tone in similar outfits, the trend begs the question, is this a secret royal family dress code, a mere coincidence, or a tradition in the making? Below, see all of the royal baby portraits that follow this seemingly unspoken dress code.&nbsp;
