Kate crowned best-dressed in Vanity Fair's list

THE Duchess of Cambridge has topped Vanity Fair's best-dressed list, earning a spot for the third year in a row.

Joining Catherine on the list is dapper brother-in-law Prince Harry, although Prince William failed to make the cut.

Australian-born Princess Mary, who favours Danish designers, was also named one of the world’s best-dressed.

Vanity Fair reports that Catherine has spent a whopping $US55,000 ($52,000) on jewellery and clothing in the past six months, and is under pressure to change outfits up to five times a day.

However, the Duchess has refused to hire a royal dresser, preferring to shop for herself at favourites like TopShop and support British designers including Alexander McQueen and Alice Temperley.

In addition to praising Catherine’s style, Vanity Fair gives a sneak peek into the royal couple’s laid-back lifestyle. The pair are enthusiastic foodies who make their own sausages and jam, and would rather stay in with a favourite DVD -  including current obsession "The Killing" - than attend high society parties, it reports.

Other famous faces to make the best-dressed list include versatile redheaded actor Jessica Chastain, who won praise for her striking black and gold Alexander McQueen frock at the Oscars. German actor Diane Kruger also made the list, as did singer Alicia Keys and designer Stella McCartney.

Along with Prince Harry, Elle McPherson’s ex, businessman Arki Busson, rapper Jay-Z, and US "Today" show host Matt Lauer were also named some of the world’s best-dressed men.

And New England Patriots quarterback Tom Brady must be getting fashion tips from supermodel wife Giselle Bundchen, after he also made the cut.
