The official account of Emilia Wickstead, who officially designed Harriet's beautiful wedding dress, has shared the post alongside a lengthy caption, including details such as how long it took to make. The pictures show Harriet – captured by photographer Mark Nicholson – at The Conservatory at Princess Anne's Gatcombe Park, which is whether the reception was held on Saturday evening.

The caption read: "Harriet Sperling wears bespoke Emilia Wickstead to marry Peter Phillips at Gatcombe Park.

"Harriet’s wedding dress is a bespoke Emilia Wickstead design, developed from initial sketch to final creation, fitted in our private salon on Sloane Street and crafted entirely by our in-house team at our West London atelier. The dress took one hundred and forty hours to make."

It continued: An intentional dialogue between tradition and modernity runs throughout the design. A square-neck column underdress is paired with a delicately cropped over-jacket that sits just above the waist, while an early 19th-century-inspired three meter train, flat and linear in silhouette, falls directly from the waist beneath the square cut-out back.

"Every element is rooted in a signature Emilia Wickstead silhouette and realised in Italian ivory crêpe, overlaid with exceptionally fine French Leavers lace featuring an all-over prairie flower motif that continues to the edge of Harriet’s veil.

"The lace is meticulously hand-applied throughout. Its heritage traces back to the early 1900s, following the invention and patenting of the revolutionary Leavers loom in Britain.

"Scalloped lace appliqué enhances the gown’s architectural, sculptural lines, extending across the neckline and cuffs. Dome buttons allow each scalloped edge to meet with precision along the centre back, underscoring the craftsmanship at the heart of the design."

The first was captured at the wedding venue, with the second taken at the couple's reception.
