Last night the royal family hosted a State Banquet for President Trump and his wife Melania during their three-day UK visit.

Prince William and Catherine, Duchess of Cambridge were also present during the formal dinner, and followed royal etiquette by dressing in their finest attire.

Kate again opted for one of her favourite designers, by wearing a white Alexander McQueen ruffled ballgown which featured a sweetheart neckline.

She also wore the blue red and white sash of the Victorian Order, the first time since being bestowed the honour by the Queen on her eighth wedding anniversary in April.

The Royal also had a the Royal Family Order brooch pinned to her chest, another honour she received last year.

As for her jewellery, she wore the Cambridge Lovers' Knot Tiara, which belonged to Princess Diana, as well as diamond and sapphire earrings which were the Queen Mother's.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
