The 'Shine Ya Light' singer made a style statement as she attended the Rimmel London 180 Years of Cool Party at the London Film Museum last night (10 October).
Her fierce tartan suit was designed by Moschino, and featured gold embroidery and black lapels. She even sported a matching bow tie!
Chunky lace-up boots and a crisp white shirt completed her striking look, with her blonde locks styled in a cute tousled bob.
Rita is currently in the midst of releasing her own capsule collection for Rimmel, so it's no surprise her make-up was totally immaculate.
She sported her trademark look of strong brows and flicked liner, adding a red pout and matching talons (from her own range, no doubt!)
The star-studded bash boasted an impressive guestlist, with attendees including fashion royalty Kate Moss, supermodel Georgia May Jagger and Aussie singer Iggy Azalea.
