The driving force behind the trend for 'boho-chic', Miller is known for her laidback, hippie-inspired look, however, she has gone for a very polished look here for the premiere of The Girl in New York.
The new mum, who gave birth to her first daughter Marlowe in July, made her red carpet return in a cream column dress which featured cape-like sleeves.
This Alessandra Rich dress was reminiscent of Gwyneth Paltrow's Tom Ford Oscars dress, and has the same superhero connotations.
Miller accessorised the pared back dress perfectly with two gold, art deco style cuffs and a tiny red lips clutch bag.
A sleek blowdry and minimal makeup finish off this flawless look.
