Italy-based fashion house Prada said it is selling the Helmut Lang brand to Japan's Link Theory Holdings as part of a strategic reorganisation.

Prada, which did not disclose a deal price, said Helmut Lang had ceased manufacturing following the autumn/winter 2006 range.

The move follows the sale of the Jil Sander label last month and signals the end of the company's multi-brand status.

Prada, which bought Helmut Lang in 1999, started sale discussions last year after the label's namesake designer quit.

The company will now focus its efforts on the core Prada label and younger sister Miu Miu, plus Azzedine Alaia and Car Shoe.

Link Theory, which is controlled by casual wear group Fast Retailing, distributes men's and women's clothing under the Theory brand.
