The Princess of Wales cut a really fashionable figure as she checked out 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 first engagement of the month - and her very first given that returning from the half-term break - in an elegant trouser match by designer Alexander McQueen for the event, in addition to a white scoop-neck top.

For her accessories, the princess chose an elegant belt, Laura Lombardi chain necklace, and a pair of sleek black heels from Prada.

But while Kate looked exceptionally classy, technically speaking, she did break an obscure design guideline throughout her check out with her choice of footwear.

'We recommend wearing useful and flat shoes,' the V&A East Storehouse's site checks out. 'The metal grid floor covering is not suitable for stilettos or kitty heels.'

However, the princess appeared completely at ease and masterfully handled the uneven floors, even while using a pair of difficult heels.

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

He added: 'She had a very energy. She was really energetic and focused. We last saw her about two years back.

'She retains this great enthusiasm and interest in imagination and making and style. It was wonderful to be able to host her.'

The mother-of-three has actually repeatedly made wearing heels look easy for many years - even while playing sports, wearing pumps on grass and attending horse racing events such as Royal Ascot.

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

She even used her beloved shoe in her very first photos 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 deal with any difficulties with ease
