Kate Middleton displayed another stylish look with a recycled fashion ensemble during the annual Order of the Garter service held on Monday, June 13.

The Duchess of Cambridge looked stunning in a red Catherine Walker coat dress at the Garter service held at the Windsor Castle on Monday. This was not the first time that the royal mother-of-two wore the designer coat, E!News reported. Kate was last seen wearing the said coat-dress while visiting the Calgary Zoo during a royal Canadian tour in 2011.

Avid royal fans may recall that, at that time, the Duchess accentuated the Catherine Walker coat with a brooch, nude colored heels, as well as a light beige clutch. For Monday’s event, Prince William’s wife partnered the striking red coat dress with a red Lord & Co hat that featured a flower accent piece. She also wore a pair of red pumps, a silver necklace and teardrop diamond earrings.

Kate’s Robinson Pelham diamond earrings were a wedding gift from parents Michael and Carole Middleton. She also wore the said jewelry piece during her wedding day in April 2011, Us Weekly magazine reported. The earrings featured a diamond that hung at the center of a teardrop design that was also encrusted with diamonds. Apart from the bespoke earrings and necklace, Prince George and Princess Charlotte’s mother also wore a diamond bracelet and a small red Alexander McQueen clutch bag.

Meanwhile, the annual event was also attended by the Duke of Cambridge, Prince Charles, as well as the Duchess of Cornwall. Initially, the said four members or the royal family were planning to walk from Windsor Castle to St. George’s chapel in a procession. However, given the forecast of rain in London on Monday, the four members of the royal family arrived at the event in their cars.

This marked the first time that the traditional carriage procession was not held during the annual Order of the Guards since 1971, as stated in the same report. A photo of the royal couple was also posted on social media through Kensington Palace’s official Instagram account.

In the photo, Kate stood alongside husband Prince William, who wore ceremonial robes during the event. Kensington also noted in its Instagram post that the Order of the Garter service was established almost 700 years ago by King Edward III. The event has also been described as the “oldest and most senior Order of Chivalry in Britain.” Kensington Palace even mentioned the Duke as the “100th Knight in the Register.”
