We're used to seeing Rihanna in her funky, youthful ensembles, so it was refreshing to see her glam-up in a stunning silk teal dress at the Stella McCartney Eveningwear Presentation and Dinner in London last night.
But, of course, there was still a slice of the signature Rihanna sex-factor - in the form of a revealing split-to-the-hip.
The custom-made Armani dress was also seductive from behind, revealing a low-cut plunge with little spaghetti straps keeping the frock together.
Rihanna dressed up the look further with a statement gold choker and a cute fringe.
What do you think of her latest dress decision?
