Her Majesty sat front row, alongside longtime royal dressmaker Angela Kelly and Vogue US Editor in Chief, Anna Wintour.
Queen Elizabeth II is making statements this year. The first, banning plastic from the full collection of her royal properties, and now - attending London Fashion Week for the very first time.
The Queen of England surprised the world's well-heeled elite at the Richard Quinn show on Tuesday night, by sitting in the front row beside fashion's most formidable magnate, Editor-in-Chief of Vogue US, Dame Anna Wintour (who did not remove her signature dark shades). To her right was her dressmaker Angela Kelly.
At 91-years-young, the Queen looked radiant, wearing a classic ice-blue matching skirt and jacket, and sharing a laugh with her 'frow' (front row) companions. She contrasted her pale twill suit with black gloves, pumps, and a patent black leather bag.
Show attendees stood when the monarch entered the room and lent over one another to get a social snap of the Queen.
Richard Quinn counts fashion avant-garde icons like Lady Gaga and activist model Adwoa Aboah as fans - and it's a little hard to imagine the blue sequin headdress, bike helmets, or leather jackets from his autumn/winter 2018 collection being added into the royal wardrobe.
However, the young up-and-coming British designer referenced the style of his guest of honour with models clad in layers of beautiful silk scarves.
The Queen wasn't only there for the spectacle - she was in attendance officially to award the designer the inaugural Queen Elizabeth II Award for British Design. The award was created to highlight the role the fashion industry plays in society and diplomacy.
