DSI London is the UK’s centre of excellence for bespoke costume production—trusted by West End theatres, Broadway, global film studios, and leading cruise lines.
From concept to curtain call, our entire process is managed in-house at our South London studio, giving us the creative flexibility and production speed that today’s costume designers demand.

We are proud to have crafted costumes for Moulin Rouge, Stranger Things, Dreamgirls, Top Hat, 42nd Street, and Death Becomes Her on Broadway, alongside productions at the Royal Opera House, and major films including Wicked and Barbie. We also support large-scale cruise entertainment and other global stage spectacles.

Every costume is handmade by our team of expert cutters, machinists, and crystallisers. Our full-service approach includes design development, fittings (both on-site and worldwide), alterations, custom dyeing, and hand-finishing. We are known for our ability to deliver the highest quality within incredibly tight deadlines—often turning around pieces under extreme time pressure, without compromising on artistry or fit.

We welcome wardrobe teams to visit our studio, where many designers are instantly inspired by our unique setup and complete in-house capability. We also regularly work under NDA with high-profile productions and maintain strict confidentiality until public release permission is granted.

If you’re a costume designer working in theatre, film, cruise, or performance, partner with DSI London for industry-leading service, design collaboration, and precision manufacturing you can trust.
