The Instagram favourite posted a picture of her new nails to the site with the caption, "Autumn nails at last! #colourcoordinated #shellac #masquerade".
The recent bride also showed off her sparkling wedding rings, which we're thinking go with everything.
True to her Chelsea roots, Millie made sure to match her mani to her classic quilted Chanel bag and her purple skirt.
She may not be in the show any more but this girl's still Made In Chelsea.
We're going to miss Millie's oh-so-stylish appearances on MIC, even if they were rather quiet and pointless.
Thank god for Instagram!
