It was plain to Lindsay was proud of the finished products as she couldn't wipe the smile off her face. The good friends were seen cosying up to one another with the American planting a gentle kiss on the Manchester-born fashion industry heavyweight at one point.

While Lindsay may be more accustomed to mingling with the capital's style set, she was joined by a host of stars from high-society, including Prince Harry's former girlfriend Astrid Harbord.

Interior designer Kelly Hoppen also attended, possibly to check out the new competition, as did the brand's business director Rosanna Falconer who looked pretty in a printed maxi dress.
