The Olsen twins are planning to expand their fashion line The Row by introducing bags and shoes.
Ashley Olsen told WWD: "It would be a proper American luxury brand, made in America, with retail businesses and maybe collaborations with other brands."
The pair set up the brand in 2007 after noticing a gap in the luxury sector.
Ashley explained: "I felt there was something missing from the marketplace. I was a shopper. I felt that basic luxury was missing. We started it very small, selling only to one store at a time, starting with Barneys New York."
