Sandy, a talented Londoner, pursued her passion for theatre design at St Martins School of Art and the Central School of Art and Design, where she honed her skills in the field. Her professional journey began in the fringe theatre scene with the National Theatre, collaborating on numerous productions, including Orders of Obedience and Rococo. This experience laid the foundation for her future work, as she went on to design sets and costumes for productions such as Lumiere and Son, Bright Side, and Culture Vulture.
As a student and rising star in the international theatre scene, Sandy held Lindsay Kemp, a renowned director, designer, and performer, in high esteem. On a whim, she phoned him to express her admiration and desire to work with him. Impressed by her work, he invited her to join his theatre company in Milan as a costume designer. Over the course of three years, Sandy worked on several notable productions, including Nijinsky, a critically acclaimed study of the life and madness of the Russian dancer Vaslav Nijinsky. She also designed costumes for The Big Parade, a tragic-comic homage to the silent film era, as well as the stage and screen adaptations of A Midsummer Night's Dream.
In 1985, Sandy transitioned to the world of video, working on numerous pop promos with director Derek Jarman. She also collaborated with him on his film Caravaggio and Zenith's For Queen and Country, solidifying her reputation as a versatile and talented designer.
