Barbie makes Sports Illustrated

After 50 years of debate over her unattainably perfect figure, Barbie is flaunting her frame in Sports Illustrated Swimsuit’s 50th anniversary issue.

The magazine issue, which comes out on Tuesday, features well-known super models like Christie Brinkley alongside Barbie wearing the black-and-white swimsuit the plastic doll wore when she made her debut in 1959.

Mattel is promoting the feature with a hashtag ‘‘unapologetic’’ on Twitter and a billboard in New York’s Times Square.

The campaign is a departure for the 55-year-old doll, which has been both beloved as a plaything and criticised as an unrealistic standard of beauty for decades.
