Swapping roles: Sienna Miller, 35, left her sex kitten alter ego at the Apollo theatre stage door in London as she prepared to take on the role of being a mother on Monday evening
Golden Globe winner Sienna kept her appearance casual and showcased her slim figure as she tucked her baggy grey T-shirt into her jeans.
Stripped of her stage costume, the screen sensation smartened up her attire with a blazer, which kept off the chill to the autumn breeze on the way home.
The fashion designer, however, proved she knew how to accessorise as she caught the eye when she sashayed out of the venue in striking scarlet brogues.
Sienna let her golden locks down in loose beachy waves and touched up her features with a light dusting of make-up.

The casual look was worlds away from Sienna's sex-kitten alter-ego in the hit play, for which she has received praise as the 'slinky and seductive' feline.
When the critics' reviews were published, Sienna came up trumps above co-star Jack O'Connell.
The Tennessee Williams play has been reinvented for The Apollo Theatre since this summer with acting duo in a husband and wife portrayal.
The Benedict Andrews' directed play centres around the sexual tension between Maggie (Miller) and her alcoholic husband Brick (O'Connell), who some believe is denial about his homosexuality.

Of Sienna's performance, The Evening Standard's Fiona Mountford wrote: 'Slinky, seductive in black slip and killer stilettos and coiled with nervous energy, Maggie prowls around the bedroom, talking almost uninterrupted for the entire first act about her loveless, and now sex-less, marriage.
'It’s a big ask of any performer and Miller turns in a faultless performance.'
As for motherhood, the West End star gave birth to her daughter Marlowe Ottoline Layng Sturridge in July 2012.
Sienna shares her little girl with her former fiancé Tom Sturridge whom she dated from 2011 to 2015.
The actress met Bennett on the set of Foxcatcher, with sources confirming to MailOnline in June that they are 'happily' still together.

The pair keep their romance under wraps, and were last seen in public at the US Open last September.
Both parties have had high-profile romances as Sienna has previously dated Jude Law and in August 2014, Bennett dated Ashley Olsen.
Meanwhile, in June the blonde beauty dismissed claims she is dating Brad Pitt, 53.
Reports claimed Sienna and Brad were 'exploring a casual summer romance' - in what would have been his first romance since splitting with Angelina Jolie , 42.
Despite the reports, sources told MailOnline the star is happily dating Bennett.
