Upon arrival, fashion designer Victoria, 50, nailed the royal curtsy as she greeted Her Majesty. Rocking a silky, teal-hued dress complete with rippling folds of fabric, the mother-of-four could be seen bobbing down with one leg crossed behind the other while shaking Camilla's hand.

The organisation's work
Also in attendance were the organisation's founder, Ms Jude Kelly CBE, as well as young women and girls involved in WOW's young people's programmes which centre on gender inequality and promoting inclusion for the next generation.
WOW is a global movement and festival run by UK charity, The WOW Foundation. Since its genesis, the organisation has worked with 33 partners across the globe, reaching over five million people in 71 different locations including Australia, Brazil, China, Egypt, Finland, Greece, Nepal, Nigeria, Pakistan, Sri Lanka, Somaliland, the UK and the USA.
A description on WOW's website reads: "Through festivals, events, schools programmes and more, WOW challenges the belief that gender equity has already been achieved – and hopes to join the dots between people, movements and ideas to change the world.
"In 2018 Jude Kelly left her role as Artistic Director of Southbank Centre to focus solely on the development of WOW as an independent charity. The WOW Foundation was established to fulfil WOW’s potential."
