The Princess of Wales‘ bespoke ensemble by the British designer included an off-white, satin coat dress with short lapels and padded buttons down the front. The garment hugged her midsection in before fluttering out over her hips. Lined with a subtle floral embroidery, the fabric was woven by Stephen Walters and Sons in Suffolk. Underneath, Middleton layered a stark white tulle skirt, adding a touch of volume to the bottom of the slim silhouette.

A closer look at Kate Middleton’s ensemble.

Middleton accented the long-form dress with a matching ivory, wide-brimmed sun hat with a thick ribbon wrapped around the head. The oversize headwear shaded her face, shielding her dark brows over her taupe smoky eye, lightly blushed cheeks and the pop of pink on her lips.

With her hair tied in a twisted half-up, half-down style, Middleton’s dangly earrings were put on full display. The pear-shaped diamonds, embellished with oak leaf handles, appeared to be the custom Robinson Pelham earrings that her parents, Carole and Michael Middleton, gifted her on her wedding day in 2011. Pulling them out of her jewelry vault was Middleton’s way of honoring her husband, Prince William, on their 15th anniversary.

The elegant ensemble was finished with a matching clutch and pointed-toe pumps — a Middleton signature. White heels, specifically, have been a favorite in her wardrobe as of late, with Middleton seemingly joining the “white-hot” shoe trend on Saturday.

Attending Trooping the Colour, she donned a pair of crisp leather pumps by her go-to footwear designer, Gianvito Rossi. Classified as the Gianvito 105 design, the handmade Italian shoes gave her Catherine Walker Lafayette Coatdress a pithy touch with their sleek 105mm stiletto heel.
