As temperatures in the UK finally began to drop this week, celebrities have been using the cooler weather as an excuse to dive into their Autumn wardrobes. That means we've seen the welcome return of long-sleeved tops, trouser suits, and statement blazers, with stars like Anne-Marie, Molly-Mae Hague, and Ashley Roberts hitting the party circuit in their latest finds. But it wasn't all about tailoring and trousers: one of the highlights of the UK red carpet calendar this week was the GQ Men of the Year Awards, which was an excuse for the likes of Adwoa Aboah [1], Rita Ora, and Maya Jama [2] to really turn up the heat in sexy ensembles that made sure the night wasn't all about the guys [3]. Finally, Ellie Goulding tied the knot with Caspar Jopling [4], and while her Chloé wedding dress definitely grabbed our attention, we were even more taken with Sienna's Miller's wedding guest style. Keep reading for your full update on all the best UK celebrity style.
