This Week's Hottest Stories

We invite you all in to the fun at the Elle 25th birthday celebrations, with a full gallery of who wore what, video footage of guests, including Vivienne Westwood, talking about their favourite magazine, and a round up of all the news from the party.

We reveal the latest designers to produce high street collections, with the unexpected news that Valentino and Gap are to become sartorial bedfellows in November- going head to head with Lanvin at H&M. Come and share in our excitement that the latter's collection will feature lipstick, meaning we can find the perfect shade of red to match our Lanvin high street silk.

We kick off our New York fashion week coverage with catwalk galleries, as well as party reports, and news about who's going to be there. You'll be sorry you missed the Chanel boutique re-launch...especially when you hear about the party bags.
