Although the collection has been officially launched, it will be available from March 8, 2012 in around 260 stores worldwide, as well as online.

I love H&M and I love Marni. I love how H&M are bringing the regal, chic clothes of Marni to everyone. actress Drew Barrymore said at the event.

Marni's collection for H&M involves a playful mix and match of colors and patterns apart from Marni's signature prints as well.

Everything goes with everything, making African prints the perfect companion to Bauhaus modernity, and sporty silhouettes sitting with more feminine shapes. The collection also includes a full range of shoes, bags and charming accessories to create a total Marni look at H&M.

Marni has a fresh take on menswear staples, with a subtle use of print and a softened use of colour.

I'm a huge fan of Marni, I have been for years. I love the whole idea of taking high fashion and making it affordable and accessible with H&M. Winona Ryder said at the event.
