London, July 19 (IANS) Pop star Rihanna's former stylist Lysa Cooper says she doesn't agree with celebrities going into the fashion industry without knowing what they're doing.
Cooper also feels that celebrities shouldn't dive into an industry that they know nothing about.
"B*******. Go to school. If you go to school, then maybe you can talk some s****," femalefirst.co.uk quoted Cooper as saying.
The designer also said that the twin actress-singers Mary-Kate and Ashley Olsen's fashion label works because they hire designers.
"The only one thing that's any good, and I hate to say it, is our girls, the twins. 'The Row'. But the reason that works, is because they hired designers," she said.
"They (the Olsens) 'yay' or 'nay' (the concepts). And they are the best line at ripping off other lines that I've ever seen. I mean they've taken designers Rick Owens, Ann Demeulemeester. But it's good. You know, they're good at it. I don't buy it, but they're good at it," she added.
Cooper, who has styled the likes of pop stars Shakira and Beyoncé Knowles, also insisted she's not interested in collaborating with anyone.
"There is enough crap being produced and enough kids making it. We don't have anywhere to put it," she said.
