London: Two unreleased collections of late singer Amy Winehouse for the British street-wear company Fred Perry will be released posthumously.

Perry, known for their signature polo shirts, had previously worked with the singer on two successful collections and will release two more, one later this year and another next year, according to reports.

"Amy was passionate and dedicated to the collaboration, and her signature style is clearly stamped across each piece," the company said in a statement.

"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," it added.

Winehouse's father Mitch Winehouse said, "When Fred Perry came to us to asked what we would like to do with the new collection, it was natural to continue."
