Harriet Sperling, the NHS nurse who married into Britain's royal family seven weeks ago, stepped out in a retro floral mini dress that has put a small London label in the spotlight.

The dress is the Patti Dress, made of linen and retailing for $695, from Wiggy Kit — a brand founded by Philippa "Wiggy" Hindmarch. It features a chinoiserie-inspired Ginger Jar motif in a vibrant, vintage floral print, according to the brand's product page. Wiggy Kit shared the photograph of Sperling wearing the dress on its official Instagram account, posting "Harriet Phillips in the Mini Patti Dress — Summer, the Wiggy Kit way" on July 27, 2026 (Town & Country).

Sperling, also referred to in some outlets as Harriet Phillips or Harriet Sperling-Phillips, married Peter Phillips on June 6. Peter is the son of Princess Anne — the Princess Royal — which places him in the line of succession to the British throne, though well down the list. The BBC described Sperling as "the newest royal" following the wedding (BBC News). Her bridal gown was a white lace creation with a dramatic veil and a diamond tiara, with reporting from People magazine that Catherine, Princess of Wales — widely known as Kate Middleton — influenced the dress's design (Marie Claire; People).

This is not Sperling's first turn in Wiggy Kit. The brand documented her wearing a dress called The Keyhole to a wedding rehearsal at All Saints Church in Kemble, Gloucestershire, on June 5 — the day before her own wedding. She also wore a Wiggy Kit piece called the Esti Set to Wimbledon in July 2025, months before the wedding made her a household name in royal-watching circles (Wiggy Kit Instagram).

For readers without a British reference point: Peter Phillips, 48, is Queen Elizabeth II's eldest grandchild. He held no royal title growing up — his mother, Princess Anne, declined titles for her children — and has worked in corporate roles, including a stint at Williams Racing. He was previously married to Autumn Kelly, with whom he shares two daughters. His marriage to Sperling, a working nurse in Britain's National Health Service, drew attention for its relative normalcy: a healthcare professional marrying into the extended royal family.

What makes the dress story resonate is the contrast. Seven weeks ago, Sperling wore a diamond tiara and a veil at a royal wedding. Now she is being photographed in a $695 linen mini dress from a brand that operates a summer pop-up shop in London. The gap between those two images — the ceremony of a royal wedding and the ease of a summer dress — is the kind of detail that tends to stick with the public.

The Patti Dress sits in Wiggy Kit's "Printed Pieces" collection alongside other named garments like The Jackie Dress. The brand lists it at £395 on its UK website, roughly $505 at current exchange rates, though the U.S. retail price is listed at $695 (Wiggy Kit).

Wiggy Kit has not commented beyond the Instagram posts. Buckingham Palace does not typically comment on the clothing choices of extended family members, and no palace statement has been issued.
