We were all saddened by the news that Kate’s new collection for Topshop was to be her last, but we were thrilled to see the supermodel at Topshop’s Oxford Street store to launch the collection to the public.

She attended the launch in a custom made 70′s inspired black jumpsuit, teamed with killer heels and raunchy red lips.

The launch incorporated a shoppping extravaganza and fans who turned up to the launch were given the opportunity to buy items from the collection before it’s official launch this morning. A DJ entertained waiting guests while they were kept happy with an array of cocktails as well as a free poster with every purchase.

To mark the event Topshop will distribute keys on Tuesday on the streets of London, Liverpool, Newcastle, Birmingham and Edinburgh to shoppers, giving them the chance to win a trunk full of the designer’s dresses. One lucky fan will also be in with the chance of winning the jumpsuit Kate wore to the launch.

The collection is on sale now from Topshop stores and Topshop.com
