The former Made In Chelsea star never disappoints with her fab wardrobe choices, and she hit the style mark once again while attending the launch of the Lynx Peace exhibition, held at The Vaults in Waterloo.
Showing off her summer glow, Millie wore a vibrant blue minidress complete with a thigh-skimming satin hemline and a black sash to nip in her waist.
Chelsea gal Millie - who is working on the launch of her own clothing collection - added a tribal-inspired statement necklace while topping her supermodel-worthy pins with pointed black boots.
Meanwhile, hubby Professor Green kept things much more casual in a pair of black trousers and comfy trainers along with a polo shirt which featured a pink floral print.
It's been a busy few days for the loved-up couple as they only returned home on Monday (18 August) after spending the weekend at V Festival in Hylands Park, Chelmsford.
Unsurprisingly, the duo had a pretty luxury camping experience after nabbing passes to Virgin Media's Louder Lounge, an exclusive hospitality area within the festival where celebs can go to relax and unwind.
Of course Millie showed off her festi-style credentials at the music event by rocking a cute cream lace dress teamed with a military jacket, while Pro Green stood out from the crowd in a bright red jacket.
