The Xtra Factor presenter was actually the host of the ceremony alongside her pal Mel B, so it was really only fair she pulled out all the stops on the fashion front!
The Radio 1 host showed off her unique sense of style in a stunning wool and crepe dress designed by Peter Pilotto, which is from the designer's Fall '14 collection.
Her fancy frock featured blue panel detailing teamed with crystal embellishment and sequins, plus long sleeves and a sophisticated below-the-knee hemline.
Unfortunately if you want to snap up her dress it'll set you back an eye-watering £1650 (boo!) but luckily, we've found a very similar version from Lavish Alice, retailing at a more reasonable £58 (hooray!).
With such a statement outfit the starlet kept the rest of her look pretty low-key, topping her pins with barely-there strappy sandals by Stuart Weitzman while flaunting a matching black mani-pedi.
Her raven locks were styled in loose waves and she worked her trademark make-up look with mega-watt false lashes and liquid liner, plus bronzed cheeks and a pop of vibrant red lipstick.
Keep up the good work, Sarah-Jane!
