Hilary Duff and GlassesUSA have teamed up with Breast Cancer Prevention Partners to mark Breast Cancer Awareness Month.

For every pair of pink framed glasses sold from the Hilary Duff x Muse collection, which launched in January, GlassesUSA will donate $5 to the charity, and Duff posted on Instagram 'Fighting breast cancer, one frame at a time!... Together, we fight for a healthier life and sustainable future'.
