Rihanna has modelled some of her own River Island clothing.

The star posted a couple of images of herself in the fashionable get-up on Instagram as she promoted her wares.

The singer, who premiered the 'Rihanna for River Island' collection recently at this year's London Fashion Week, can be seen wearing a long black dress.

Another photo sees Rihanna don a revealing denim top, showing off her slender figure. Tweeting about the latter, the 'Stay' songstress said:

"Cropped denim farmer brown top#RIHANNAforRIVERISLAND (photo cred:@leleboo_phucku)."

Response from fans were somewhat mixed, with one Instagram user commenting:

"It looks cool rih, it fresh ideas for street fashion."

Another person, however, said: "Awful outfit #knackerstyle."
