Rihanna launched her first fashion collection in the UK because she feels British kids have the best style in the world.
"These kids inspired the high-end designers - they say what's cool.
"So why not to go to the source when you want to be ahead of the trend and create something inspirational and fresh? That's why I wanted to work with River Island."
The 24-year-old Bajan singer's collection features neon coloured separates, saucy thigh-high splits and crop tops.
"I've wanted to design my own fashion line for a very long time now; it's been something I've thought about since I started loving fashion.
"Every time I saw a garment on the rack there was something I wanted to change, so I felt like the only way I could do that was by designing the perfect thing for me."
