Johansson is involved in every aspect of the line, from designing to the ad campaign. "I can draw, but I certainly can't do sketches that approximate the designs," she explained. What Johansson can do is rummage through Reebok's archives — she favors collections from the 1970s — and collaborate with Reebok's design team to put her ideas to work. "The great thing about working with Reebok is their resources are huge," she said. "If I find a retro fabric, they can help rework it into something technically right for today." "I am really wary of that whole persona-in-the-public-eye selling a product. I absolutely would never put out a piece of clothing that I wouldn't wear. It was important to me that I had complete control over the whole project, and Reebok was really open to that", Scarlett commented.

The advertising campaign breaks in spring 2007. It will include TV, print, online and OOH executions. Scarlett's initial contract is for three years, but is renewable.

• "I like to do yoga and stretch out, so we will probably do a bunch of stuff for that. Things you can wear to the yoga studio and then to coffee with your friends. I like the idea of exercise and aerobics being glamorous: Olivia Newton John and women exercising in false eyelashes."

• "There is so much pressure to look a certain way and to be thin, and I think part of that comes from fitting into clothing or not fitting into clothing. I am basically designing clothing for my friends, and a lot of my friends are also regular girls with lovely curves and feminine figures."

• Paul Harrington (Reebok's President and CEO): "Reebok is thrilled to partner with Scarlett because she is a world renowned style icon and truly an inspiration for today's young women. Scarlett embodies the pulse points of our brand - individuality, authenticity and a life lived to the fullest in perpetual motion. These characteristics make her the perfect fit for our new women's footwear and apparel collection and also for our exciting new women's campaign."
