Muir began her working life in the shops of Liberty and Jaeger in London where she developed her skills as a dressmaker and designer. In 1966 she set up her own business and put 'craft and quality' before innovation. Her skills in cutting and draping material were exceptional but she preferred to be called a 'dressmaker' rather than 'designer'. Her label is still a byword for sensual, immaculately structured garments. This photograph shows Muir with a model, the composition and the lighting combined creates a beautifully structured image, accentuating the dress the model wears. This was part of a series of photographs Swannell took of famous designers and their muses.
