The former Girls Aloud singer opted for a white crop top, which perfectly showed off her abs – jealous much?
Sarah earned herself extra style points by adding checked monochrome trousers to her ensemble and even kept with the black and white theme with her shoe choice – sporting a gorgeous pair of white hued heels, which featured a cute bow.
While we think Sarah looks extremely chic, we couldn't help wondering if she felt the chill in her tiny top?! But the 32-year-old must be a pro at braving the cold, as Sarah wore another skimpy number just last week.
The blonde star accessorised her outfit with a pair of aviator shades and some silver rings. She also gave us utter bag envy, toting around her essentials in an oversized black Aspinal of London number – lucky Sarah!
As for make-up, Sarah's skin looked absolutely flawless and she kept her pout nude and glossy for a glam finish. Her talons were painted a cool black to tie in with her monochrome look.
Good effort, Sarah!
