The Rehab star has teamed up with Fred Perry to create a 17-piece retro-inspired wardrobe, consisting of capri trousers, cardigans and mini-dresses.
"I'm really excited - we've been working on it for a while and it's great to see it finally come to fruition," she said.
The troubled performer is said to have had a very hands-on role in the creation of the range.
Fred Perry marketing director Richard Martin said: "Amy has been wearing Fred Perry for years, so we were aware she was a genuine fan of the brand.
"Amy has a unique sense of style that reflects the brand's own historical reference points," he told Women's Wear Daily.
"We had three major design meetings where she was closely involved in product style selection and the application of fabric, colour and styling details.
"Amy gave crucial input on proportion, colour and fit. The range clearly has Amy's handwriting."
