The campaign, created by digital agency Profero, is challenging a number of influential bloggers to make their own Limited Collection, as the retailer attempts to carve out a more distinctive personality for its sub-brands.
Marc Bolland, Marks & Spencer chief executive, laid out his vision for creating more distinct identities for the company's Limited Collection, Per Una and Autograph clothing sub-brands last November.
The Facebook campaign encourages the fashion bloggers to wear items from the Limited Collection for a week and create a new look every day.
Bloggers including and will be asked to post pictures of their outfit choices each day and discuss what they like about the range.
Greater engagement will be encouraged by inviting M&S Facebook fans and the fashion bloggers' readers to vote on their favourite outfits. The blogger with the most votes will win a trip to Paris.
The competition will end next week and will be supported by rich video banners pushing the Limited Collection range.
The banners will feature the work of British photographer John Rankin Waddell, which will run on premium digital fashion sites including Glamour, Look and Cosmo.
