Lily James just wore the perfect holiday party outfit, so start planning yours now

Lily James not only attended the holiday event of our dreams, but she wore the perfect outfit. James performed the Christmas tree light switch-on at Harrods in London this week. The event celebrated Harrods’ partnership with Burberry in A Very British Fairy Tale, the holiday display in the windows at the department store.

Wearing a black lace dress with a keyhole cutout slit and long slit, an ivory coat and metallic pumps, Lily James looked like a muse from holiday heaven.

We love how her red poppy pin stands out against her off-white cashmere coat with bell sleeves. And we love how her metallic shoes play off her little black dress. Every piece in her picture-perfect get up is from the new Burberry collection for Harrods.

The 27-year-old Cinderella actress, whose real name is Lily Chloe Ninette Thomson (!), was accompanied by her boyfriend Matt Smith.

She posed by the interactive window display. It allows visitors to interact with a sensory window, through a touch-trigger mechanic and motion sensor.

Lily’s look may be even more perfect without her coat. We love those black lace sleeves!

James is the face of the My Burberry Black fragrance, and stars in the new holiday film “The Tale of Thomas Burberry.”

Celebrating the company’s 160th anniversary, the three-minute film tells the story of its founder Thomas Burberry. James stars alongside Domhnall Gleeson, Sienna Miller, and Dominic West. It’s epic and beautiful and you must watch it now.

We’re praying to the movie gods that this gets made into a feature.
