[10] Stone has opened shows for Giles Deacon, Isabel Marant, Christopher Kane, Fendi, and MaxMara, and closed for Chanel, Diesel, Marc Jacobs, Stella McCartney, and Balmain.

[11] In the February 2009 edition of Vogue Paris, which featured Stone on the cover, she said she does not like the runway and that her unusually small feet for a person of her size do not fit in shoes.

[13] Stone made her American Vogue debut on the May 2009 cover alongside Liya Kebede, Anna Jagodzinska, Natalia Vodianova, Caroline Trentini, Jourdan Dunn, Raquel Zimmermann, Sasha Pivovarova, Natasha Poly, Karen Elson, and Isabeli Fontana as one of the "Faces of the Moment."

[14] An international racial controversy arose when she appeared in an editorial for French's Vogue October 2009 issue with her face and body blackened.

[7] In 2010, Stone replaced Sasha Pivovarova as the new face for Prada's fragrance Infusion d'Iris, shot by Steven Meisel.

[4] This same year her look sparked a trend in: blonde, gap-toothed, big-lipped models like Georgia May Jagger, Lindsey Wixson, and Ashley Smith.

It marked the first time in years the fashion house had chosen to use one model for three of its brands, and Stone would be exclusive to CKI for all apparel advertising and runway appearances for fall.

[citation needed] Stone was part of Vogue UK's first multi-cover in the publication's 95 years, landing one of the three May 2011 covers in celebration of the Wedding of Prince William of Wales and Kate Middleton.
