So who is Adidas by Stella McCartney?Â
McCartney is a terrific fashion designer who graduated in 1995 with a degree in Fashion Design from Central St. Martins.  Her college graduation collection was bought by stores such as Neiman Marcus and Bergdorg Goodman.  In 1997 she was appointed the Creative Director of Chloe fashion house in Paris, which is a very prestigious appointment.  In 2001, Stella McCartney launched her own fashion line that included women’s ready-to wear range, accessories, eye-wear, perfume (Stella) and an organic skin care line called Care.  She has since collaborated with Adidas on Adidas by Stella McCartney (yes, they’re banking on you knowing her last name).
The Stella McCartney line might be new to us in the U.S but she has worked with Adidas sportswear since 2004 to design high performance sportswear for women, including running, gym, yoga, cycling, tennis, swim and surfing; also included is kids wear.  This is a big deal because Adidas is the largest sportswear manufacturer in Europe and the second biggest in the world after NIKE.
The Adidas by Stella McCartney line is found in Stella McCartney stores.  Her first U.S. store opened in Florida and she now has stores in Dallas, Las Vegas, Los Angles, Miami, Michigan, New York, San Francisco.  You can also find her high-end line at department stores such as Bergdofgoodman, Nordstrom, Nieman Marcus, Saks Fifths Avenue, Adidas and Macy’s.  Internationally, her stores are in London, Shangai, Singapore, and Moscow.  Of course, if you’re not a brick and mortar shopper then you can shop online at any of aforementioned  stores or Shopbop.com, Adidas.com, and StellaMcCartney.com.
