Millie put a picture of her look on Instagram, writing: "Today I dressed like a wannabe Cher from Clueless #tartan #turtleneck."
Teaming her cute tartan miniskirt with a black polo neck and thigh high boots, we think Millie looked adorable!
The former Made In Chelsea star was obviously a fan of 1995 hit movie Clueless when she was younger... and let's face it, who wasn't?!
Cher Horowitz, played by Alicia Silverstone, was a mega-rich teenager who spent her days giving less fortunate girls makeovers and picking her outfits with the help of a computerised wardrobe which made the rest of us SO. JEALOUS.
So it's no wonder Millie, aka the new Mrs Manderson, took inspiration from 90s Alicia for her look.
Millie had quite a busy day in her Clueless-esque outfit. First up, she took delivery of her new range of Millie's Lashes and excitedly announced: "Yay finally they are here! My limited edition @millieslashes, perfect for the party season."
Then Millie hit the hairdressers to get her locks whipped into shape.
Posting a picture of her smooth hair on Instagram, Mille said: "Thank you @miguapo78 my hair feels silky soft after a rahua omega9 hair mask @joshwoodcolour."
Finally, she rounded off her day with some homemade courgette noodles with pesto and prawns. Sounds dreamy, Millie!
