Just like her phenomenal mother-in-law, the late Princess Diana, 33-year-old Kate Middleton proves that she is a fashionable force to beat as she wows the crowd during the Cinema and Television Benevolent Fund's Royal Film Performance of the James Bond movie Spectre.

The Duke's fashionable wife and escort graced the glamorous black tie CTBF Royal Film Performance in her ice-blue diaphanous gown that modestly covered the Duchess' but still retained a sexy and flirty element thanks to the backless ensemble showing through the chiffon drapes, The Daily Mail reports.

The Jenny Packham outfit was an elegant number that featured a V-neck and a bejeweled waistband that sparkled coolly against the smooth fabric. The pastel blue gown got on famously with a pair of pale blue jewel drop earrings by Robinson Pelham, the Duchess' sapphire ring that famously belonged to Diana, and a glittering Jenny Packham silver clutch. Kate's deep brown locks were locked in an adorable plaited bun, but it was her Jimmy Choo platform high heels that commanded the most attention.

Apparently, Kate has famously worn the same pair of silver heels to various events in the past, since 2011 during at least four different gala events: a red carpet event at LA, the 2012 countdown to the London Olympic Games, the Tusk foundation gala dinner at The Royal Society in London in 2013 and the James Bond premiere.

Whether it is a sign of economy or smart choice is up for debate, though the shoes truly suit Kate Middleton's dainty feet.

The duke and duchess, followed by a rugged looking Prince Harry looking smug in black tie, met the cast of the film, foremost of which was the main star himself, Daniel Craig. Christoph Waltz, Lea Seydoux, Ben Wishaw, Naomie Harris, David Bautista, Monica Bellucci, Andrew Scott and Ralph Fiennes were also there to meet the UK's royals.

The President of the CTBF, Barry Jenkins OBE, was pleased that the World Premiere of Spectre was selected as The CTBF Royal Film Performance 2015.

Meanwhile, Hollywood Life reports that the resplendently fashionable Kate was an expert at hiding the important news from her adoring public. Despite donning the daring gown, rumors are rife that the eldest Middleton is pregnant with the third royal child. The Palace has yet to confirm whether these rumors are at all true.
