Amy Winehouse's designs for label Fred Perry will be released posthumously.
The British streetwear company - famed for their iconic polo shirts, synonymous with teenagers of the 60s and 70s and the early Skinhead moment - had previously worked with the singer, who died suddenly last month, on two successful collections and will release two more, one later this year and another in 2012.
The company said in a statement: "Amy was passionate and dedicated to the collaboration, and her signature style is clearly stamped across each piece."
"Amy's royalties and fees from both collections will be donated to the soon-to-be-established Amy Winehouse Foundation. Fred Perry will also make a seasonal donation to the Foundation.
Amy's father Mitch Winehouse added: "When Fred Perry came to us to ask what we would like to do with the new collection it was natural to continue."
"Amy loved working on both collections, and would want them to be made available. All the money we make and the donation that Fred Perry will give will go straight into to the Amy Winehouse Foundation, which we are setting up to help children and young people in her name."
Amy was said to have been fully involved with the design of her collections, the first of which was a 50s inspired set which included twinsets, gingham, pencil skirts and capri pants in October 2010.
She then collaborated on a follow up Spring/Summer collection which was Hawaiian-inspired and launched in March this year.
Richard Martin, a marketing manager from Fred Perry, told Harper's Bazaar Amy was a "delight" to work with.
He said: "Bright, passionate, and dedicated, with strong ideas of exactly what it was that she wanted from the range. Detailing, fabrics-she was all over it."
