Whether it was Luna Lovegood’s whimsical party dress that was designed to resemble a Christmas tree or how the colours of Lord Voldemort’s malevolent robes were hints about the seven Horcruxes, costumes played a vital role in telling the Harry Potter stories on screen.

Now fans can discover the magic of costume creation at Warner Bros. Studio Tour London – The Making of Harry Potter this March and April.

With only 30 guests per session, this 45-minute exclusive workshop will reveal the secret world of costume design and how the choice of fabrics, colour and fit played a vital role in creating some of your favourite characters.

Exploring some of the wizarding world’s most iconic costumes, you will be able to witness the evolving styles of Hogwarts uniforms, gaze upon Cedric Diggory’s Triwizard robes and marvel at Hagrid’s oversized attire.

Led by experts, these sessions will also include behind-the-scenes pieces and subtle design details rarely seen by the public. Secrets will be revealed such as the surprising colour of Severus Snape’s costume, the hidden meaning in Narcissa Malfoy’s coat and how Sirius Black’s distinctive coat foreshadowed his Animagus form. That’s just the tip of the iceberg!

With 2026 marking the 25th anniversary of Harry Potter and the Philosopher’s Stone, the workshop will also be taking fans back to where the magic began, showcasing the costume that Harry Potter was wearing the very first time we met him.

Not only will you leave with a newfound knowledge of the art of storytelling through costume, but you will also take home a commemorative Mastering the Magic collectable pin badge.

Plus, after the workshop, fans will be led into the Great Hall to start their full Studio Tour experience – exploring the sets and filmmaking secrets that helped to create the wonder of the wizarding world in all eight Harry Potter films.

Mastering the Magic workshops will run exclusively on select dates across March and April 2026 and tickets go on sale on 5th February 2026. All tickets must be pre-booked, and all features are included in the ticket price. All tickets can be purchased from the Studio Tour website.
