Nathalie Rykiel, the President of Sonia Rykiel (and the founder's daughter), loves two things: frozen yogurt ("I eat it twice a day in New York!") and knits ("An absolute must for all women"). We sat down with her to discuss her newest collaboration with H&M, a knitwear line she describes as "flagship Rykiel, but still modern and lovely." Featuring bold color, sparkle and her hallmark stripes, the collection of separates is heavy on the fun and the miniature version for children (a first for H&M) is unbelievably cute. Rykiel's favorite pieces include a multi-striped oversize sweater dress (middle), a one-shoulder LBD and a logo sweater that "simply must be worn with jeans." The collection retails from $4 for multi-striped socks to $55 for dresses and hits stores February 20th.
