My thesis catalogues the changes brought about in folk costume as a result of entering a theatre environment. My aim is to present this process through the first major folk costume evolution on stage associated with the Gyöngyösbokréta movement, through the work of Gitta Mallász, including the contemporary folk costumes of Edit Szűcs (through the repertoire of the Hungarian State Folk Ensemble). I also review Gitta Mallász's career as a graphic designer. Her graphic design work was greatly influenced by the nationalist mood of the 1950s, which led to the spread of decorative folk motifs and the golden age of Hungarian folk dance theatre. In my thesis I discuss the appropriate application of modern technologies present in the work of Edit Szűcs, which not only enhance the dancer's appearance, but also provide functional help. Whether it is laser cutting or the use of smart materials, her solutions form a bridge between folk costume and the viewer that is indispensable in today's context.
