Giving her love of head-to-toe black an injection of military vibes, the Made In Chelsea fave has looked to Zara's cool woolen coat.
She paired the gold-buttoned number with prints, tailored separates and her dreamy Dune handbag.
If you fancy splashing your Christmas cash on Millie's Zara coat, you're in luck as it's been knocked down to £99.99 in the January sale. We'd suggest keeping an eye out for any further reductions, too! Shop the coat here.
