But yesterday at the reception for Charles’ 50th anniversary as the Prince of Wales, Kensington Palace took the unusual step of not divulging who Kate’s dress was created by.
Aides would only comment that the duchess’ pale blue high-neck midi dress was designed by a “private dressmaker.”
It’s not the first time the palace have remained tight-lipped about one of Kate’s outfits.

During her debut appearance at the Christmas Day church service in Sandringham in 2011, Kate wore a aubergine hued coat designed by “an independent British dressmaker.”
The designer of a pale yellow lace dress the duchess wore on her royal tour of Australia in 2014, was also not disclosed.
It’s unclear whether the pieces have all been created by the same dressmaker, but there has been a couple of theories as to who the person is.
The Queen’s dressmaker, Angela Kelly is one of the names rumoured to be behind Kate’s latest outfit.
Liverpool-born Kelly has been designing Her Majesty’s outfits since 2002, but began working for her as one of her dressers in 1992.
Kelly is considered to be the Queen’s ‘gatekeeper’ and enjoys a close relationship with the monarch.
Reports at the time of Kate and William’s Australia tour suggested that Kelly helped the duchess prepare for the trip, so it wouldn’t be a surprise if she has created the odd bespoke piece for her.
As Kate prepares for her future role as William’s Queen Consort, there’s the possibility that she may move away from couture and high street pieces in favour of a personal tailor.
