Meghan and Kate dazzle as the 'Fab Four' reunites for latest royal appearance

Ah, the life of a royal.

One day you’re shaking hands with the Archbishop of Canterbury at Prince Louis’s christening, the next you’re staring up at the sky to watch a military flyover at Buckingham Palace.

A day after gathering for the youngest royal heir’s special church service, Prince William, Kate Middleton, Prince Harry, and Meghan Markle helped celebrate the 100th anniversary of the Royal Air Force.

The royal brothers wore their military uniforms as they arrived at Westminster Abbey Tuesday morning for a service marking the centenary.

Prince William formerly served as an RAF search-and-rescue pilot, while Prince Harry received helicopter training from the RAF during his time in the Army Air Corps.

And what of their wives? For the second day in a row, Kate pulled an Alexander McQueen number from her closet.

Her icy mint coat is the same style she wore to the royal wedding on May 19, albeit in a different color.

The duchess accessorised with nude heels, a silvery fascinator with a bow and floral accents, and the prestigious Air Cadets Dacre brooch, which is the highest award a female cadet can receive.

Meghan, meanwhile, went for a darker look in a retro-style, bespoke Dior dress featuring her go-to bateau neckline.

The Duchess of Sussex, who traveled to Dublin Tuesday evening with Prince Harry, paired the dark navy dress with a matching fascinator by Stephen Jones, gold-and-diamond Cartier earrings, and, like her sister-in-law, nude pumps.
