Zara-Clad Kate Wows Crowds At Barlow Concert

The Duchess of Cambridge was one of the stars of the show at a concert in aid of two royal charities when she appeared in a high street dress costing just £69.99.

Zara-clad Kate and husband Willliam joined the Prince of Wales and the Duchess of Cornwall at the Royal Albert Hall to see X Factor judge Gary Barlow perform.

It was the first time the two royal couples had attended a public event together.

Kate teamed the Zara dress - which bears a remarkable similarity to an Erdem one she also owns - with black tights, a black Ralph Lauren jacket and high heels.

The nude and black lace dress is now sold out online, but is still available in some stores, Zara confirmed.

A spokeswoman for the shop said it "was popular even before Kate wore it", but refused to confirm sales figures.

A skirt version of the dress is still available online and in stores, priced at £39.99.

Kate previously wore one of the high street store's creations - a £49.99 cornflower blue dress - with the same jacket on the day following her wedding to William. That dress quickly sold out across the country.

Minutes before going on stage, Barlow told the second-in-line to the throne: "I hope you enjoy tonight and I hope it's not too loud."

William replied jokingly: "The louder the better, the louder the better."

When the royal couples took their seats a huge cheer went up from the audience who got to their feet and the prince acknowledged the reception by smiling and waving a programme in the air.

The event will raise funds for Charles' charity the Prince's Trust and the charitable body William runs with his brother - The Foundation of Prince William and Prince Harry.

The show was the second of two consecutive nights at the Royal Albert Hall with both performances expected to raise £400,000 for the good causes.

After striding on stage to cheers the singer waved up towards his royal guests during the opening verses of The Greatest Day.

And after the first few numbers, Barlow greeted William and Kate's party saying: "Good evening to our beautiful royal family."

He added: "All the money goes to a fantastic cause so we're killing two birds with one stone."

He sung A Million Love Songs, Pray, Nobody Else, among other hits.

Strictly Come Dancing contestant Jason Donovan was one of the acts who appeared with Barlow along with Olly Murs, Lulu, and X Factor's Marcus Collins who is mentored by the Take That frontman.

During the concert William, Kate and Camilla could be seen clapping along to the music while Charles tapped his hand on the armrest of his chair.
