Rihanna launched her new collection for fashion chain River Island last night (4 March), at the chain's Oxford Street shop.

The 'Unapologetic' singer was an hour late to the catwalk fashion show - which took place in the window of the store - and arrived wearing a clinging black dress with a thigh slit and cut out back.

The collection, which has come under fire from critics for being 'brazen' and 'aggressively sexual', was debuted at London Fashion Week and is now available for fans to buy.

Speaking about the collection at the launch, Rihanna said, "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. I mean, I'm so happy. I can't even believe it.

"I would wear everything here. I was being a little bit selfish. I designed everything that I would want to wear, and for the women that I'm with. 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."

River Island's Josie Roscop said, "She came to fittings, we would fit it on models, make sure that it was hanging correctly. We chose the fabrics with her. So it just flowed in a very sort of smooth development process."

Rihanna tweeted about the event last night, writing, "In London launching my #RihannaForRiverIsland collection tonight at Oxford Street! #phuckyoclothingline."

Rihanna got changed into a white t-shirt and jeans after the event in order to hit the afterparty, at DSTRKT night club, along with Will Smith, X Factor's Jahmene Douglas and Made in Chelsea's Spencer Matthews, Oliver Proudlock and Rosie Fortescue.
