The costume in a musical works as a full-fledged hero of the frame: it sets the rhythm, emphasizes character, and turns the song into a spectacle. The lecture will explore how the screen fashion of the genre has changed - from Hollywood classics to films of recent decades. A musical always relies on the synchrony of movement, music, light, and image. But it is often the costume that makes the cinematic world recognizable at first glance: the shine of the fabric, the line of the silhouette, the color score, and even the way the clothing moves with the actor help the viewer read the character's personality faster than any explanation. The conversation will begin with early Hollywood traditions and gradually lead to modern films. The focus will be on films such as "Zuzu", "Cylinder", "Singing in the Rain", "West Side Story", "The Umbrellas of Cherbourg", "Grease", "Chicago", "Mamma Mia!", "La La Land", and others.
