No matter whether you have one or ten Christmas parties in the diary, working out what to wear is often equal parts excitement and trepidation. So we naturally look to the women whose style we trust most for inspiration—and after last night, Alexa Chung is firmly leading the pack.
The event? The Reformation x Pixie Geldof Christmas cocktail party. The guest list? Jack Guinness, Amelia Windsor, Maddi Waterhouse—and the OG British cool girl Alexa, of course. The outfit? A vintage-feeling silk nightdress (Reformation, naturally) that has already shot to the top of every fashion fan’s wish list, styled with a green knit casually tied at the waist and a wool coat layered on top.
