The former Made In Chelsea star gave model of the moment Kendall Jenner a run for her money when she stepped out in this absolutely gorgeous suede mini dress that featured a thigh-skimming hemline, exposing her envy inducing pins.
Just look at them!
Turning the city streets into her very own catwalk, Millie looked every inch the fashionista in the 60s inspired, tan hued frock that boasted cutesy metallic buttons along the front and a sharp triangle collar - WE LOVE.
Mills teamed her eye-popping look with a pair of matching sky-scraper heels as she sashayed elegantly into the venue to toast her new book with pals including MIC's Rosie Fortescue.
And what can we expect? A fun-filled guide on how to emulating her oh-so-glam lifestyle of course! Rather excitingly, Made will feature all the best fashion, beauty, food and fitness tips that our Mills has picked up from spending time in fancy Chelsea salon chairs and lavish eateries over the years.
The reality beauty looked to make-up artist Justine Jenkins to glam her up for the glitzy event and we cannot get enough of her super-sultry smoky eye! An advocate of the au naturale vibe, Millie turned a serious amount of heads with her new look as she posed for the dazzled paps.
Celeb hairdresser Kirsty O' Brien was on hand to primp and preen Millie's locks into effortless, beachy waves - but don't worry - we're pretty certain that her page turner will be filled to the brim with tricks on how to nab the style for ourselves.
We can't wait to land our hands on it when it launches on 10th September!
