H&M can do no wrong. In the past, the high street retailer has collaborated with everyone from Karl Lagerfeld to their most recent line with Jimmy Choo, not to mention the highly anticipated lingerie and knitwear collaboration with Sonia Rykiel.

Just when we thought that was good enough, the retailer has announced that the Sonia Rykiel collection will be officially unveiled and celebrated with a big runway show in Paris on December 1, days before the collection hits stores.

The show will take place at the Grand Palais, the place of choice for Karl Lagerfeld for Chanel's runway shows, and will showcase the full line including both lingerie and knitwear.

If you cast your mind back to the star studded Stella McCartney launch and the Matthew Williamson party with Grace Jones in attendance, speculation for the font row of the show is already in full swing.

We are pleased to reveal that The Fash Pack will be attendance and will be reporting and tweeting live from the event for you so stay tuned.

Just when you thought H&M couldn't get any better, they go and surprise us (again). The high street retailer who has been responsible for bringing the likes of Karl Lagerfeld, Stella McCartney and Matthew Williamson to the high street at affordable prices, have got another designer collaboration in the pipeline.

This morning they announced that they are set to collaborate with French icon, Sonia Rykiel. An exclusive range of lingerie and accessories from the brand will be released in 1,500 H&M stores worldwide on the 5th December and will also be available in leading Sonia Rykiel boutiques. If that wasn't special enough, the collaboration marks the first time the high street chain has incorporated lingerie into a collaboration.
