Kate arrives at the Royal Albert Hall in a Zara dress & Ralph Lauren jacket 

There are nods of approval throughout Grazia Daily Towers this morning and it's all down to Kate Middleton. The Duchess of Cambridge arrived at the Royal Albert Hall in London last night and guess what? She's championing her beloved British highstreet once again courtesy of this chic dress from Zara.

Kate with Prince William, Prince Charles and Camilla

Yep, DoC threw together this black and white ensemble for a swanky evening with her hubby and parents-in-law, Charles and Camilla. The foursome arrived on the red carpet to watch Gary Barlow perform, in an event that raised money for The Prince’s Trust and The Foundation of Prince William and Prince Harry, and could be seen enjoying the concert from the Royal box, obvs.

Kate teamed her tulip dress, covered in a layer of lace, with black tights, matching heels and an oh-so sleek Ralph Lauren jacket (the very same she wore on the day after the Royal Wedding, FYI). It's a youthful yet sophisticated look and oh-so K-Middy, don't you agree?

As you know, the Duchess is developing quite a penchant for the highstreet heavyhitter. Who could forget the blue Zara frock she wore after getting hitched (yep, the one she wore with the same RL jacket)? And it was only last month that she was snapped shopping in the store, no doubt picking out the dress for last night.

The skirt version of Kate's dress

Naturally, the dress has already sold out online - but fear not! If you've picked up the latest issue of Grazia, you'll have seen the sophisticated skirt in our Fashion Charts is the VERY.SAME style as Kate's frock. And, gob-smackingly, it's not sold out (yet). You can nab it now on www.zara.com for a bargaintastic £39.99.

Race you there!
