From fashion design’s big stars such as Matthew Williamson, who presented timelessly elegant cuts combined with colorful prints, and Vivienne Westwood’s punky chic to London’s new stars Mark Fast and Kinder Aggugini, the edgy capital’s fashion week kick-off didn’t disappoint.

According WWD, Lady Gaga will perform at a New York Fashion Week launch party for the new Givenchy Play men’s fragrance at The Box on September 15th!

The event is being hosted by Out magazine. Lady Gaga is also rumored to perform at Marc Jacobs’ party the previous Monday evening.

Milan Fashion Week kicks off Wednesday in an atmosphere of gloom and doom with some 10 fewer shows in the lineup because of the global financial crisis.

While 95 fashion houses staged shows a year ago, this year’s programme has attracted only 79. A total of 93 brands showed their summer 2009 collections here last September.

For London Fashion Week, the Victoria and Albert Museum of art and design will present an “anthology of hats” bringing together more than 300 pieces from around the world.

This exhibition, a collaboration between the V&A and the radical hat designer Stephen Jones, will open on February 24 and will be arranged in four main themes, following the life of a hat through the stages of inspiration, creation, the salon, and on, to the client who wears it.
