Louise Flanagan is originally from England. After completing her ballet training at the Royal Ballet School, she danced at the Vanemuine Theatre in Estonia. She then shifted her focus to costume design, earning a degree from Middlesex University and completing a professional tailoring apprenticeship. She went on to work as a costume tailor on numerous high-profile films, musicals, and operas in England. Since 2013, she has been working as a freelance costume designer for dance and opera, collaborating with choreographers and directors such as Jörg Mannes, Kinsun Chan, Cathy Marston, Marcel Leemann, Terence Kohler, Sam Brown, Lillian Stillwell, Mauro Astolfi, Yuki Mori, Andreas Heise, Francesca Frassinelli, Peter Leung, Dimo Kirilov Milev, and Ihsan Rustem. Her work has been featured in international companies including the Bavarian State Ballet, Ballett Zürich, Ballett am Rhein, Stanislavsky Ballet Moscow, Theater Magdeburg, Theater Münster, Theater Regensburg, Oper Graz, Theater St. Gallen, Ballet du Capitole Toulouse, and the Origen Cultural Festival.
She also assisted costume designer Emma Ryott at Ballett Zürich, the Bolshoi Theatre in Moscow, and the Staatsballett Berlin.
Louise received a grant from the German Dance Association (Dachverband Tanz Deutschland) to research and develop a database of sustainably produced fabrics for dance costumes. By sharing and implementing her findings, she aims to reduce the environmental impact of new productions— taking a step toward greater ecological sustainability in dance and theatre.
