Stella McCartney has partnered with Netflix's Sex Education for the Toilet, Teeth, Tits (TTT) campaign in support of Breast Cancer Awareness Month this October, which 'encourages people of all ages to conduct regular breast self-examinations during their morning routines'.

In support of the campaign, Stella McCartney's winter 2021 ready-to-wear collection includes TTT campaign T-shirts, and the Stella McCartney Cares Foundation will donate a post-mastectomy bra to breast cancer patients for every T-shirt sold. The British fashion designer features in the campaign alongside Sex Education cast members Aimee Lou Wood, Chinenye Ezeudu and Mimi Keene, and commented 'Breast cancer is a horrific disease that has brought so much pain to women and families around the world, including my own, and I am proud to partner with a global service like Netflix and the wonderful talent of Sex Education so that our Breast Cancer Awareness 2021 campaign can reach people everywhere'.
