Sienna Miller and her boyfriend Oli Green attended the Haider Ackermann x Augustinus Bader x Tish Weinstock dinner on Thursday (October 12) in London.
The last time we saw the British actress on the red carpet, she let it be known that she was pregnant with her second child.
But on this occasion, you probably couldn’t tell on account of her wearing this Taller Marmo California kaftan mini dress from the Pre-Fall 2023 collection.
And the reason we wouldn’t have questioned anything is because this loose-fitted dress takes us back to her carefree, boho era.
The only thing missing are her Isabel Marant ankle boots, because she has the Gucci bamboo bag.
