The Princess of Wales cut a very stylish figure as she visited the brand-new V&A East Storehouse in London the other day - but one element of her outfit appeared to break the gown code.

Kate, 43, marched for her very first engagement of the month - and her very first because returning from the half-term break - in an elegant trouser suit by designer Alexander McQueen for the event, along with a white scoop-neck top.

For her devices, the princess selected an elegant belt, Laura Lombardi chain necklace, and a set of smooth black heels from Prada.

But while Kate looked incredibly elegant, technically speaking, she did break an obscure design rule during her visit with her choice of footwear.

'We recommend using practical clothes and flat shoes,' the V&A East Storehouse's site reads. 'The metal grid flooring is not appropriate for stilettos or kitty heels.'

However, the princess appeared entirely at ease and masterfully managed the uneven floors, even while using a set of challenging heels.

When inquired about Kate's option of shoes, Tristram Hunt, the director of the V&A, told PEOPLE publication: 'She is a pro! She dealt with that!'

He added: 'She had an incredibly energy. She was really energetic and focused. We last saw her about 2 years back.

'She maintains this terrific passion and interest in creativity and making and style. It was terrific to be able to host her.'

The mother-of-three has actually consistently made wearing heels look simple over the years - even while playing sports, using pumps on grass and participating in horse racing occasions such as Royal Ascot.

In 2012, Kate even used heels to play a video game of hockey and, more just recently in 2022, kicked a football in heels throughout an engagement with her hubby Prince William.

She even used her precious shoe in her first images with Prince Louis in 2018 as she stepped outside the Lindo Wing of St Mary's Hospital.

Depsite misgivings, the princess was such a 'pro' in her heels that she was able to handle any challenges with ease
