While one pic of Peaches posing in just her pants and a vest top, another has her lying back on a bed in seductive pose.
"Raising awareness of this very important cause, which affects so many women of all ages, is something I feel very passionately about and that's why I wanted to support the Peacocks Breast Cancer Awareness range," the Daily Mail quoted her, as saying.
Looking sultry in the all-pink clothing, she said that by supporting the cause the people can also look good.
"By purchasing the product, you not only support the charity but you get to look great at the same time," she said.
The product sale will go as a donation Cancer Research, UK.
"We are very pleased that Peaches is supporting our campaign. This fantastic range will raise awareness and vital funds for research into breast cancer," a Peacocks spokeswoman said.
The limited edition range of pink products includes jewellery, bags and even a "doggy coat".
