Today, the British actress announced she has helped design a 33-piece summer capsule collection which takes its cues from her own wardrobe. No prizes for guessing, then, it is a treasure trove of boho-chic which might as well have strutted out of Glastonbury circa 2004. Yes, that means coin belts (£29.

50), block-printed quilt jackets (£65), matching sarongs (£25) and beaded, floaty white vest tops (£49.50) all make for headline acts. It comes after Miller became the face of the British retailer’s autumn winter campaign last year in a move that deepens their relationship and follows Alexa Chung’s footsteps, who also designed a successful range for M&S in 2016.

In December, Miller gave birth to her second child, and first with boyfriend Oli Green . But she has made sure to make a mark on 2024’s biggest red carpets, nonetheless. Appearing at the Met Gala and the Cannes Film Festival, Miller doubled down on her love of all things flimsy and fluttering, and on booth occasions wore Chloé, the Parisian house which has recently turned back to bohemia thanks to new creative director Chemena Kamali .

Kamali’s silk mousseline, ruffled Chloé frocks might set you back £3,900, but Miller has created similar designs – in baby blue and ivory cott.
