Building on previous efforts made through Relay for Life, about 45 women - and one man - have dared to bare almost-all to raise additional funds for the Cancer Council, while sharing a powerful message around body positivity.

The "madwives" calendar was officially launched on Friday and features women of all shapes, sizes, and ages posing in a range of settings and costumes.

With more than 400 copies printed and almost half already sold, midwife Penni Ives said everyone involved had embraced the concept - even though some took a bit of convincing.

"At first a few staff members thought 'why would you want to do that for, who is going to buy calendars of half naked midwives?'," she said.

"But after participating in the whole process, they said 'that was fantastic. Thanks for encouraging me to do it'."

After being inspired by a similar calendar put together by a Country Women's Association group more than 20 years ago, Ms Ives said she had always had the idea in the back of her mind as a possible team building exercise.

Featuring members of the LGH's Holman and QVMU Troopers Relay for Life team, the calendar features no shortage of creativity - including some revealing hospital gowns.

As midwife Kylie Burns explained, the project also served as a fun way to encourage women to be more comfortable in their own skin.

"Being body aware and feeling comfortable to feel your own boobs, that is part of the philosophy of the Cancer Council," she said.

"Definitely we are all a bit fun and quirky here [LGH], but we deal with women when they are vulnerable.

"Our theme throughout this has been friendship and accepting our bodies for what they are.

"Looking at the pictures, I think there is pretty much joy in every one of them."

The Madwives Calendar supporting Relay for Life is available for $25 from Rhubarb for Gifts' stores at Invermay and Riverside.
