The September issue of the monthly title, which will hit shelves on Thursday 30 July, will include a redesign, new features and a bid to revive its editorial coverage of sex and relationships.
Jackie Newcombe, managing director of IPC Southbank, admitted Marie Claire had let its coverage of relationships "slip" and was looking to make it a sexier title.
Key changes to the title include a new shopping section, called Straight into Style; Heart & Soul, which claims to offer readers a sophisticated approach to sex and relationships; new regular beauty features, such as "How to Look Expensive", and the return of food pages across the lifestyle section.
According to the latest set of ABC circulation figures for the second half of last year, Marie Claire recorded a 4.8% decline in circulation, in comparison with the second half of 2007, to 314,259 copies per month.
The redesign of the magazine will be accompanied by a rise of 10p in the cover price, to £3.40, and the relaunch will be supported by a £1m marketing push.
