Mattel has rarely remarked on its Barbie dolls controversial body proportions, but a new interview with FastCo Design finds one of its top designers defending the exaggerated shape. Barbie’s body was never designed to be realistic, Barbie design VP Kim Culmone tells FastCo Design. She was designed for girls to easily dress and undress. Beyond just allowing the clothing to come on and off the doll, Culmone also says that Barbie tiny figure helps Mattel sew and shape common fabrics at such a small scale. Though Barbies shape has changed slightly over the years — even making its proportions modestly more realistic — Culmone suggests that Mattel would prefer not to change its design all that much.
