Sienna Miller looked effortlessly stylish as she headed out in New York City on Sunday.
The actress, 42, wore a cropped biker jacket that she teamed with an Adidas bucket hat while running errands.
She layered a cream fluffy jumper underneath to keep out the cold and added a pair of wide leg jeans.
Sienna topped off her outfit with a grey Prada handbag and a pair of chunky heeled leather boots.
She has been in the city to promote Joe Weiland and Finn Constantine’s short film Marion, on which she served as executive producer.
On Friday Sienna made sure all eyes were on her as she posed for photos at the Marion screening.

The actress looked nothing short of sensational as she cut a chic figure in a tan power suit consisting of a single-breasted blazer and matching tailored trousers.
She teamed a skin-tight black camisole top with her stylish suit and added inches to her frame with a pair of brown leather boots.
To complete her look, she added a blue mini handbag before further accessorising with a gold-toned flower pendant necklace and hoop earrings.
The star hosted the event at the Cinema by NeueHouse and several stars attended.
The mother-of-two, who welcomed her second child and first with boyfriend Oli Green back in December, looked to be enjoying a child-free day as she posed up a storm at the glitzy bash.
Marion focuses on the French tradition of bull-jumping at La Course Landaise, with the synopsis reading: ‘As Marion prepares, being the only woman in the team, the film explores her battle against misogyny and prejudiced attitudes.
‘A journey of one woman through an all-male world – juggling motherhood and the contentious pursuit of her passion. The film blends fiction and reality, creating a captivating thirteen minutes of tension.’
Sienna was last seen with her boyfriend, 27, last month as the pair enjoyed a romantic holiday together in Saint-Tropez.

The couple’s sunny trip comes after they welcomed their first child together, a daughter, in December 2023.
Sienna already has 12-year-old daughter Marlowe from her previous relationship with actor Tom Sturridge, 38.
Her new boyfriend, Oli, an actor who is 15 years her junior, is just like her — instinctive and a free spirit.
In an interview earlier this year, she explained: ‘I think you either live your life with caution or you take risks.’
She added that whatever success, or otherwise, her choices are met with, she is finally at peace.
‘For the longest time, I felt the need to really prove something, and I can see that reflected in the choices that I made. I pursued roles that were very heavy and very dramatic and challenging emotionally because I felt that I was probably seen as frivolous. I’m now completely over that.’
