With a degree in art history and training in fashion design at the Cours Berçot, Alain Blanchot began working as a costume designer for film and advertising.
He quickly developed an interest in stage performances, designing costumes for singers from atypical worlds such as Brigitte Fontaine, Sapho, Anna Karina and Ingrid Caven. His taste for live performance led him to work on original productions. In 2004, he began working with director Benjamin Lazar on the costumes for Le Bourgeois Gentilhomme, a candlelit comedy-ballet for Le Poème Harmonique. He continued to explore the sumptuous and fanciful codes of Baroque opera with Landi's Sant' Alessio, directed by William Christie for Les Arts Florissants with Philippe Jaroussky, and Lully's Cadmus et Hermione at the Opéra-Comique. In this way, he refined his work on material and colour.
Since then, Alain Blanchot has taken part in numerous productions of baroque opera (Handel's Rinaldo, Lully's Phaeton, Cavalli's Egisto, John Blow's Venus and Adonis, etc.) in Paris (Opéra-Comique, Théâtre des Champs-Elysées, Châtelet, Athenée, etc.) and abroad (Germany, Russia, New York, Sweden, Spain, Italy, Czech Republic, Monte Carlo, etc.). He has also worked on contemporary opera creations (Cachafaz after Copy, Au web ce soir, live opera on the internet, Lalala, etc.) and on classical works such as Cendrillon, Carmen, Pelléas et Mélisande and La Nonne Sanglante, meeting many directors, including Louise Moaty, David Bobee, Robert Carsen, Jean-Romain Vesperini, Basil Twist, Aurélien Bory and Lilo Baur. ... and creating wonderful complicities with singers such as Léa Dessandre, Jakub Orlinski, Julie Fuchs, Michael Spyres, Véronique Gens and Philippe Jaroussky...
Alain Blanchot has also collaborated with the House of Guerlain to design the uniforms for the staff of the Guerlain boutique and institute on the Champs-Elysées.
His costumes are regularly exhibited at the Centre National du Costume de Scène.
In 2023, alongside Benjamin Lazar and Philippe Jaroussky, he created Sartorio's Orfeo at the Théâtre de l'Athénée before designing the costumes for Henry VIII by Saint Saens, directed by Jean Romain Vesperini at Bard College in New York, a work acclaimed by the New York Times.
In 2024, in addition to Lully's Armide at the Opéra-Comique, there will be Der Freischütz in Kiel, Germany, Boris Godounov at the Grand Théâtre d'Avignon, La Vie Parisienne and Le Comte Ory at the Grand Théâtre de Québec.
