Advertisers are also being offered sponsorship opportunities from in-store shopping competitions, fashion shows and blogs, to cocktail parties, fashion workshops, tickets to events and consumer makeovers. 

As part of the festival, photographer Mary McCartney will produce an exhibition of iconic photographs to celebrate what fashion and beauty means to the British consumer. 

The full list of titles involved in the event includes Harper’s Bazaar, Esquire, Prima, Good Housekeeping, Zest, Reveal, Best, Cosmo Bride, You and Your Wedding and Men’s Health. Participating websites will include Handbag.com, cosmopolitan.co.uk and allaboutyou.com.

Jessica Burley, managing director of NatMag, said: “30 Days of Fashion and Beauty is a celebration of fashion and beauty that provides a unique multi-media, cross-platform opportunity for advertisers to engage with audiences.  We’ll be using the power of our titles and brand loyalty to create distinctive and exciting opportunities and are talking to our key partners about ways they can get involved in this huge project.”

Duncan Edwards, chief executive of NatMag, added: “30 Days of Fashion and Beauty is a concept inspired by a similar initiative launched by the Hearst Corporation in New York in 2006. It was so popular that is it now a permanent annual fixture in New York, Los Angeles and Chicago.  Earlier this year, our joint-venture partner ACP Magazines in Australia also ran a similar month-long event which was hugely successful.  Following this terrific track record, we’ve decided to bring this dynamic concept to the UK for 2008.”

Money raised from the event will be donated to the UK’s leading breast cancer charities.
