The Duchess of Cambridge continued her reign over the style set last night when she stepped out in an oyster grey silk Jenny Packham gown.

But it's not the first time we've seen the Grecian-inspired design. The label is a favourite with a host of Hollywood stars - most notably Angelina Jolie, who wore the same style in red to a premiere in May.

It is little surprise that the dress has proved such a favourite. It is demure enough for formal Royal occasions in that is shows no cleavage, and the folds of fabric and flowing skirt do not cling too much. But the asymmetric neckline reveals a sexy flash of shoulder.

The ribbon tie at the waist gives the gown a feminine silhouette - and of course demonstrates how slim both women are.

Both, of course, also share long dark hair, worn loose, in keeping with the carefree feel of the dress.

Such a statement dress requires little embellishment in terms of jewellery - but what there was, dazzled.

As well as her famous sapphire and diamond engagement ring, Catherine wore Art Deco-style diamond chandelier earrings and a diamond bracelet.

Angelina's bling was no less impressive, with a large gold cocktail ring and coordinating stud earrings.

But that is where the similarities ended. Catherine's dress, which bore an all-important poppy pin to mark Remembrance Day, was a heavy silk, catching the light.

Angelina's instead, was chiffon, causing the fabric folds to fall in a slightly different way. A slight ruffle beneath the exposed shoulder also differed from Catherine's version.

Royal seal of approval: Catherine wore Jenny Packham's designs three times this summer alone. At the ARK gala in London in June (left), in Calgary, Canada in July (centre) and at the polo in Santa Barbara (right)

But they are not the only high-profile figures to fall for Jenny Packham's creations. Though Catherine is most regularly seen in the label, the Brit designer now has an extensive star fan base.

Vanessa Hudgens, Emma Roberts, Miley Cyrus and Taylor Swift are among the bright young things to favour her eveningwear

Once known for just bridalwear, Ms Packham has started showing at New York Fashion Week - the most recent show in September saw Mandy Moore sit front row.

Angelina looks like a wax figure, all her red carpets she looks waxy, a heavy cream that hides all the imperfections ... and Kate's shots are candid while Angelina's are on the red carpet, where the lighting is supposed to make the subjects look their best. Second, Angelina isn't natural, she'd had 2 nose jobs, eye work and check implants and uses hair extensions in the back to give her thin hair volume and length, while Kate has had no work done. Not that I care but since we've become a society that evaluates people's worth by their looks, let's at least be honest on what it takes for them to look as they do.

Can't say I'm much of a fan of Angelina, but she does knock the lazy, posing, preening, gloating "Kate" into a cocked hat. James, I'm afraid your irony is wasted on the drooling indiscriminate sycophants on these threads, but it made me smile!

The only way Kate is channelling Angelina that I can see is that she's also woman and wearing a dress, that's where the similarities end I'm afraid!

reading some of these comments people saying Jolie has more elegance!?! really??? the woman wore blood in a tube and snogged her bro!!!! Also looks alot like skeitore these days with claw hands, Kate is much more classy, real and has alot more elegance hands down! Oh and she doesnt go round the world collecting kids either! Go ahead with the red arrows as so many people are blinded by this homewreaking woman.

Must have been a bloke who wrote this and not a fashion designer for sure.

Kate dresses like a 12 year old and is no way in the same "gorgeous" league as Angelina
