H&M has announced its next designer collaboration will be with Italian fashion house Marni.

The Swedish high street retailer caused global hysteria earlier this month when the Versace for H&M line went on sale, and its earlier collaborations with high-end brands such as Lanvin and Sonia Rykiel have been similarly successful.

Rumors had been suggesting the next H&M collaboration could be with Tom Ford, after H&M's creative adviser Margareta van den Bosch described him as "a very interesting name."

However, the brand revealed in a press release Tuesday, November 29 that its Spring 2012 designer partnership will be with Marni.

The label's founder and creative director Consuelo Castiglioni has created the clothing and accessories line inspired by Marni's original prints, which is for both men and women.

It will be available in 260 stores worldwide and online as of March 8, 2012.

"I wanted to create a true Marni wardrobe by revisiting all our favorite pieces in signature fabrics and prints. As always, I love juxtaposing prints and colors, mixing modern tribal with Bauhaus graphic adding sporty utilitarian elements," explained Castiglioni.

2012 will also see the release of a second round of designs from Versace creative director Donatella, whose Fall 2012 sold out in just half an hour in some stores.

Last week a spokesperson for H&M confirmed Donatella's Spring pre-collection will be available January 19, although only in countries where H&M has an e-commerce site such as the UK, Germany, the Netherlands, Denmark, Sweden and Norway.
