Rihanna looked dashing in a thigh-high split black dress while attending the Rihanna for River Island Collection Launch at the Oxford Street River Island store in London.

The We Found Love singer combined it with a white jacket and Manolo Blahnik heels. Rihanna who debuted her first fashion collection at the London Fashion Week last month said that designing the collection was 'a dream'.

"From where we started, from jotting these down on napkins and pieces of paper in the hotel room in the middle of the night. It's scary," she said, "I mean, I'm so happy. I can't even believe it,'' she said.

Rihanna admitted she was a "little bit selfish" when she was designing her range of clothing for River Island.

"I designed everything that I would want to wear, and for the women that I'm with. I'm with a large group of women who have different sizes, different tastes, different body types. I wanted to design something that everybody could wear because I wanted all my friends to have something too, but I'd still wear everything," the Caribbean singer added.

The Diamonds singer also defined the typical woman she is hoping to dress.

"Sassy, fun and someone who's not afraid of having fun with fashion, but everything is simple, everything is classic. I wanted to make things that ten years from now we'll not know what era, they'll not have an era attached to it or a brand or whatever,'' she said.
