The Saturdays singer went solo for the evening without her fellow bandmates, joining the likes of Millie Mackintosh and Daisy Lowe at the launch of American Eagle Outfitters' new London store.
Showcasing her chic yet oh-so-effortless sense of style, Vanessa sported a pair of high-waisted, blue-wash jeans complete with ripped knees for a distressed feel.
The 'What About Us' singer added a smart touch to her denim by tucking in a burgundy red floaty blouse while topping her pins with towering pointed court heels.
She channelled Rihanna on the nail front, opting for super-long stiletto talons lacquered a bright red hue, sweeping her tumbling brunette locks into a loose updo.
And we're just a little bit obsessed with her Saint Laurent Monogramme Satchel handbag, although with an eye-watering price tag of £1,590, we probably won't be snapping one up anytime soon!
To top off her look, Vanessa decorated her chocolate peepers with a circle of warm brown eyeshadow along with mega-curly, mascara-clad lashes, adding a dab of bronzer to help define her cheekbones along with a sweep of pretty rosy pink lipstick.
We can't get enough of this outfit - good work, Vanessa!
