The former Made In Chelsea star gave us a major case of style envy (as always!) while attending the Pretty Ballerinas spring/summer '15 launch in Covent Garden.
The starlet ditched the figure-hugging frocks in favour of a stunning black jumpsuit, which featured a sheer overlay covered in a chevron print.
Her one-piece also boasted a plunging, wrap-over neckline to amp up the va-va-voom, along with a cinched-in tie waist and loose culotte-style trousers.
Keeping the colour scheme neutral, Mills added length to her pins with black platform peep-toe heels while flaunting minimal jewellery with just a few silver rings.
And the fashion designer showed off her stunning natural beauty by keeping her beauty look fuss-free, whipping her caramel locks into a high bun.
Millie - who has her own collection of false lashes - defined her peepers with winged-out, 1960s-style eyeliner, adding fluttery falsies and nude gloss, all topped off with a touch of peach on her cheeks. Gorgeous!
The Chelsea fashionista - who is married to rapper Professor Green - was later joined at the event's after-party by her MIC pal and BFF Rosie Fortescue, who looked fab in leather trousers paired with a Chanel tweed bag.
