And just like the Duchess of Cambridge proved earlier today when she debuted her royal bundle of joy in a stylish Jenny Packham dress, the historic occasion calls for a little fashionable flair.
So as many of us raise a cup of tea—or pint!—to toast the new heir to the British throne, we've rounded up a fun selection of Union Jack-emblazoned clothes and accessories for royal baby enthusiasts to wear while celebrating the royal birth.
Die-hard royal watchers will appreciate a glam clutch from one of the new mother's fave designers—Alexander McQueen—while sentimentalists at heart will go gaga over an oh-so-adorable heart-shaped Union Jack sleeveless tee from Wildfox.
And since the royal baby was born at the height of summer, we've also included a patriotic one-piece for those of you hailing the wee Prince of Cambridge poolside or at the beach.
From snazzy shades and shoes to cool nail decals and trendy shorts, we've got you covered with our Union Jack style guide!
