Swedish retail brand H&M has released a series of exclusive collaborations this summer by teaming with a number of fashion brands and designers. From Hawaiian-inspired resort wear to summer swimwear, the brand has unveiled an array of interesting summer collections for fashion lovers across the world.

Topping the list of collaborations is the much-anticipated accessory collaboration with fashion icon and legendary fashion director, Anna Dello Russo. Known for her flamboyant sense of style, Dello Russo has created a special collection of accessories exclusively for H&M.

The entire collection will be unveiled on 4 October, 2012 during the peak of the global Fashion Week tour in approximately 140 stores worldwide and online.

"As a stylist I know accessorisation is essential: it is the personal touch to any outfit. With these pieces everybody can have fun, turning an ordinary day into a fantastic fashion day," states Anna Dello Russo.

Additionally, H&M is launching H&M for Water, a collection of Hawaiian-inspired resort wear. The collection features dresses and skirts for women in a palm print, as well as bandeau tops and matching skirts in a nostalgic floral print. A part of the benefits from the sale will be given to WaterAid, which helps provide clean water and sanitation to some of the world's poorest areas.

The collection also features retro swimwear and an entire range of accessories, such as see-through beach bags and bandanas. For men, the palm-print shirt combined with printed shorts, sunglasses and sandals, is a summer essential.

For summer 2012, the softest of pastel shades are the top choice of Ann-Sofie Johansson, H&M's Head of Design.

"Our summer collection's pretty pastels are just what I want to wear right now," states Ann-Sofie. "A knee length skirt with pleats, a wide waistband, or elaborate embroidery looks great together with a matching top."

The swimwear collection, on the other hand, features vibrant shades and patterns of paradise found on bikinis and halter neck swimsuits. Simple block colours of hot pink and acid green make a bold statement, alongside Hawaiian, floral, and paisley prints. There are also feminine strapless one-pieces, as well as scuba-inspired bodies for a sporty feel.
