The shirts will be available in stores from 27 July. A quarter of the proceeds of each sale will be donated to cervical-cancer charity Jo's Trust.
The T-shirts were designed by two competition-winning Look readers.
The project was overseen by Look senior marketing manager Tara Steadman and New Look's group design director, Babara Horspool.
About 2800 new cases of cervical cancer are diagnosed in the UK each year; about 1000 women die from the disease.
