Duchess of Cambridge, née Kate Middleton, is a style icon in the truest sense of the word, sending fashionable fans running to recreate each elegant look she wears – and now, adding one more style is easier than ever. For a limited time, Rue La La has reintroduced one of the exact gowns Kate has worn.

The Diane von Furstenberg Zarita lace gown hasn’t been available in recent months, but on Friday Rue La La put the black version which Kate wore back on sale. For those who wanted to recreate Kate’s designer look without the price tag, there was further good news as the dress retailed for $439, half of its original price.

The stylish royal was first spotted in the gorgeous floor-length gown when she and Prince William headed to the Royal Variety Performance in November last year.

Looking the epitome of glamour, Kate, who was pregnant with Princess Charlotte at the time, wore her glossy brunette locks up in a low chignon, with not one hair out of place. The Duchess complemented her chic updo with smokey eye make-up, and a hint of blusher.

Her accessories were minimal but dazzling, with the 33-year-old opting for a black sequinned clutch bag, Lola blue topaz hoop earrings by Kiki McDonough and, of course, her beautiful engagement ring.

It comes as no surprise that one of Kate’s dresses has gone back on sale – the style icon often sees her outfits selling out within minutes of being identified in what has been dubbed ‘The Kate Effect’.

Earlier this year, she caused a spike in sales of yellow dresses after she wore a cream and yellow bespoke Jenny Packham creation when she and Prince William introduced little Princess Charlotte to the world outside the Lindo Wing in May.

Online retailer eBay have revealed that in the UK, there has been a 58 per cent sales increase for yellow floral patterned dresses following her appearance. In Australia, there has been even more of a frenzy with a 208 per cent increase, as well as a 131 per cent sales increase for nude heels, to match the pair of nude Jimmy Choo pumps the Duchess wore.
