Chanel SketchesLesage is perhaps the most famous because of it's work with Chanel. Yes, it is the house that embroiders Chanel. But Lesage has worked with many other legendary designers, Yves Saint Laurent and Elsa Schiaparelli being two (they still have samples from Elsa-all the way back to the 1930's!)
They also work with new and emerging designers, Mary Katrantzou being the most notable. As a side note, I am obsessed with her, and was almost more excited to see a garden-print dress being embellished than a tweed being made.
One of the best parts was learning about how the designers collaborate with the craftspeople- designers will come and give the theme, and then the craftsperson will create samples based on the theme and what they think the designer is looking for. The designer will then pick their favorite, and a series of drawings and patterns and samples are made. Once the embroidery is complete, the pieces go back to their respective fashion houses and are assembled there. Pretty cool, right?
