Sonia Rykiel's debut lingerie range for H&M caused a frenzy a few months ago. Now, we can reveal a video preview of Rykiel's new knitwear collection for the retailer. It comes amid a startling confession that the only reason Sonia Rykiel collaborated with H&M was because they were copying them.

"Are you asking if H&M has used my designs?," creative director, Nathalie Rykiel asked Nylon. "Well, yes, of course! They copy me all the time! Finally I said, 'Look, if you want your girls to wear Sonia Rykiel from H&M, let's let them have the real thing!'"

You can get your hands on Rykiel's stripey knits at H&M stores from 20 February.
