The publisher claims that, as well as being the first fashion brand extension for the UK edition of the fashion-led women's monthly, Elle Collections is the first standalone title to focus solely on catwalk shows.
The picture-led magazine will showcase the season's trends, look behind the scenes at shows and encourage readers to re-create the latest catwalk looks.
Hachette will aim Elle Collections both at existing Elle readers and the broader market of fashion-conscious magazine buyers, typically ABC1 women aged 25 to 35.
Unlike Elle, which is available in standard and compact sizes, it will adopt an extra large glossy format of 255mm x 330mm, similar to that of US style and celebrity title W, and will retail at £5.
The debut issue, which covers the autumn and winter collections for 2006, goes on sale on 19 July with a print run of 50,000.
In the July to December ABCs, parent title Elle grew its circulation by 3% year on year to 208,132, its highest sales figure in four years.
