The GQ Men of the Year Awards is an annual knees-up for the slickest trailblazers in film, politics, music and fashion.
While male attendees, including Greg James and Sam Smith, put flamboyant twists on their humble suit and tie combinations via swirling bow ties and lace shirting, the women channelled an androgynous aesthetic in tailored suits and cigarette trousers.
One side of the room saw Victoria Beckham in an ivory double-breasted variation while another witnessed the refined cut of Arizona Muse's cropped sparkling suit by Brunello Cucinelli.
There was no shortage of gowns, though, with actor Fanning in beguiling Dolce & Gabbana florals while model Neelam Gill sparkled in Julien Macdonald metallics.
