Autumn was all about the bob. But heading into winter, celebs seem to be ruminating on a new question: to go a luxurious winter blonde, or deepen to a glossy mocha? It seems Lily James is team brunette, a series of recent outings in New York revealing she’s ditched her usual summery ombré for the rich chocolatey shade.

Coupled with an Italian midi cut styled by David von Cannon, the beauty of James’s mocha lies in its multidimensionality, its espresso base ribboned with burnt caramel and cinnamon hues. As Stephen Buller and Anita Rice, founders of Buller and Rice salon, previously explained to British , these layered tones are what the shade feel so luxurious. “[Multidimensionality] is important throughout the lengths and ends so it reflects light and feels expensive rather than looking like one solid block of dark colour,” they said. “This also gives clients who have had years of balayage an opportunity to go darker without feeling as though they’re simply covering everything up.”

And James is in good company, Zoë Kravitz and Hailey Bieber are both on board. Winter blondes, you have 24 hours to respond.
