The par-tay, hosted by designer label Miu Miu, saw the fashion pack's finest out in force and proved just why they're a bunch of trend-setters.
Looking fresh-faced and effortlessly chic, supermodel Kate played it cool in a wintery velvet coat over a pair of super-shiny trousers and stilettos boots. Mossy teamed her usual all-black with a silvery floral print camisole and matching scarf.
Alexa's look couldn't have been further from Kate's, but she looked just (if not more) as glam. The model and former T4 presenter went retro in a 1950s-style tea dress made good with a lace bodice and lime green puffball skirt. Polishing off her look with a boxy black bag and a pair of simple Mary Jane's we think Alexa may have just pipped Kate to the fashion post.
