Rihanna Launches Fashion Line for River Island in London

Last Monday Rihanna celebrated the launch of her new fashion line, "Rihanna for River Island," at River Island's chic Oxford Street store in London. As expected, a huge crowd gathered for the launch.

Rihanna, 25, looked super chic in a floor-length, long-sleeved black dress with a slit up the side, one of her creations. According to E! News, Rihanna's line is reasonably priced, with items starting at $45.

Rihanna will be marrying longtime boyfriend Chris Brown this summer.
