When Prince Christian was born on October 15, 2005, his fate was sealed.

Unlike other children of his generation, this brown-haired, blue-eyed royal would grow up in the public eye.

With yellow marble walls illuminated by Venetian glass chandeliers, the space is truly imposing.

Guests can choose to wear either ballgowns, military dress uniforms, or white tie attire.

Military honors are welcome, and tiaras are encouraged.

As of this writing, it remains unclear who exactly will don what in terms of headwear.

Princess Maria Chiara

According to Danish royal protocol, princesses do not receive their first tiaras until their 18th birthday.

Time will tell if he chooses a similar ensemble.

And, from what we can tell, the film itself will be quite formal.
