Comme for H&M: Hurry Up

The woman who designed this now wants you to shop at H&M. Immediately. Rei Kawakubo of the Japanese line Comme des Garçons has created a capsule collection for the high-street retailer, available today at 200 stores worldwide.

The 50-piece collection is heavy on black, white, navy...and polka dots. There's both women's wear and menswear in stock, plus accessories and a unisex scent. Prices peak at £200 but start as low as £15, making Rei's gothic and boundary-pushing style credit-crunch friendly.

Previous H&M collaborations (with designers including Viktor & Rolf and Stella McCartney) have sold out in days. Shoppers went wild when the Comme des Garçons collection debuted at the retailer's new store in Harajuku, Tokyo, on Saturday. Especially those who had been waiting outside since Tuesday.

Viktor & Rolf Plus One

What's better than two Dutch designers with a surrealistic bent and prankster tendencies? Two of those designers and an Italian industrialist who could give them serious cash to propel them into the major fashion players they want to be.

Diesel creator Renzo Rosso has taken over the majority stake of Viktor & Rolf, but the financial details of the deal aren't being released. Rosso had been negotiating with Viktor Horsting and Rolf Snoeren since 2006 and now is in talks with Belgian design label Maison Martin Margiela, which his holding company took over six years ago.

"It's a new chapter to start building on the brand and to focus on creativity." Rolf told WWD. "We needed to team up with a strong partner to realise our dreams...It's like a marriage: You have to be sure you have the right partner."

Viktor & Rolf Dress up the Barbican

Is the collar of your favourite dress made of satin pillows? Do you think wedding dresses look just a bit smarter with red-glitter messages down the front? Lucky you - The House of Viktor & Rolf, on display until 21 September at The Barbican, shows off 16 years worth of surrealistic Dutch clothing design.

This is Britain's first solo exhibition for Viktor Horsting and Rolf Snoeren, who can count Tilda Swinton and Rosin Murphy among their fans. The gallery's two-story retrospective is packed with couture-clad mannequins and video screens with runway shows playing on a loop, but the main feature is a giant white house with tiny dolls dressed in some of the designers' signature looks.

Known for bizarre antics like launching a PR campaign for a fake perfume and installing an upside-down interior in their Milan boutique, Viktor & Rolf have an outlandish but appealing range at the Barbican. It's just £8 to get in, so you'll have plenty of money leftover to buy a bottle of the designers' Flowerbomb perfume on the way out.
