Melanie C and J.B. Gill are among the stars who have donated items to the Fashion Saves Lives sale.
The sale, which is hosted by Save the Children ambassadors Erin O'Connor and Mary Portas, will be held exclusively on Mary's Living & Giving eBay store from 18th - 28th June and also includes bespoke collections.
Mary, 54, said: ''By buying a pre-loved item from the Mary's Living & Giving's ebay shop you not only give the clothes a new lease of life but you also help save the lives of children who are needlessly dying from preventable causes like pneumonia or malaria.''
Erin, 37, is ''extremely proud'' to be involved with the fundraiser and is thrilled to be able to help children around the world who would otherwise die from preventable diseases.
She said: ''I am extremely proud to be hosting such an amazing collection of fashionable donations with Mary and the team at Save the Children. By purchasing a pre-loved piece for your child, you can help ensure that other children around the world have the chance to live a healthy life.
''Visiting India with the charity and learning that 6.3 million children currently die each year from easily treatable causes has left me feeling determined that every child should have the chance to lead the long and healthy life we all strive for, for our own children.''
