Designer labels including Alexander McQueen, Chanel, Mulberry, Stella McCartney, Prada, Burberry, Miu Miu and Christian Louboutin join high street brands - from Topshop and Reiss, to Gap and Urban Outfitters - and boutiques and department stores, including Matches, Selfridges, Net-A-Porter, Browns, Harrods and Harvey Nichols, for the shopping extravaganza. Every single company is offering special online events, prizes, discounts or free gifts - and with every single purchase you'll be helping a charity of your choice.

Online Fashion Week will launch for the first time next month, in what is to be the biggest shopping extravaganza the web has ever seen.

SEE THE LATEST EVENT ACTION

Following the hugely successful Fashion's Night In online event in November last year - which raised over £40,000 for charity in six hours by encouraging readers to shop the best, exclusive buys on the web via a blog on VOGUE.COM that ran from 6pm until midnight - this year's event will involve more online retailers, include more high fashion styling advice, feature even more exciting exclusive content and - hopefully - raise a good deal more money for charity over the course of a full working week. On Monday December 5 until Friday December 9, we'll be blogging about the latest offers and discounts, one-off, covetable collections and the best online buys.

Updated Friday 28 October, 9.16am:  We are one step closer to  Online Fashion Week today as the  registration page launches to welcome retailers to the event. Brands from Alexander McQueen and Chanel to Topshop, and from Prada and H&M to MY-WARDROBE.COM, are already on board and are currently planning their activities for a week of virtual events. Cheryl Cole's new collection of shoes is set to be unveiled during OFW; Burberry's pioneering online department is already planning something bigger and better than ever for the Week; VOGUE.COM blogger Livia Firth has already signed her Eco Age boutique up; whilst shops including Browns, Net-A-Porter and Matches are preparing to bring their many international designer names to OFW.
