Fashion is targeting breast cancer in a whole new way this time: tie dye. Sass & Bide has lent its exclusive tie dye tank dress ($170), to as part of the retailer's third installment of Fashion Targets Breast Cancer.

Breast cancer is a topic that hits close to home for Sass & Bide co-founder Heidi Middleton, who was diagnosed with it in February 2007. But she and partner Sarah-Jane Clarke were ambassadors for the organization long before that.
