The former Made In Chelsea star looked super-svelte in the white textured mini dress, £39, from Inspired by at Miss Selfridge.
It looks great paired with heels, a box clutch and statement necklace. We love the Russian style faux fur hat.
Perfect look for evening.
For day Mrs Professor Green picked this cosy jacket, £89, which she styled with a bobble hat and chunky knit. Loving her look, and the fact that it's cruelty free.
Miilie has started the new year sticking to a strict keep fit and diet plan, but as these pics show, she really doesn't need to!
This morning the reality star tweeted: "Breakfast today. A spinach, chorizo and tomato omelette,using two egg whites."
Her fitness regime is obviously stepping up too as she tweeted: "Very excited to be working with @xboxuk to get ultra-fit this January with @XboxFitness this morning."
She's now represented by the same management as Amy Childs, Gemma Collins and Peter Andre.
Hmmm - we wonder if this means she'll be appearing on Splash! or appearing in her own reality or fashion show anytime soon.
Watch this space.
