Watch: Behind the Scenes at the TIME Barbie Cover Shoot

TIME worked with some unconventional models for their latest cover photo shoot: Mattel’s new Barbies. The iconic doll now comes in three sizes petite, tall and curvy. It’s the first time in the brand’s 57 years that Barbie’s body has undergone such a dramatic change and it follows the addition of a range of new skin tones and hair textures in 2015.

The new dolls were escorted from Mattel’s headquarters in California to photographer Kenji Aoki’s studio in New York by Mary Jordan who has been the company’s Barbie stylist for the last 23 years. While on set, Jordan gave TIME an inside look into what it takes to get Barbie ready for her closeup. From knitting needles and jewelry pins to hair gel and toupe tape, Jordan has the tools to prepare Barbie for her many appearances.
