Have you ever seen Yves Saint Laurent's famous Mondrian dress? No, so take the time to visit her in the presentation of the collections of the Yves Saint Laurent Museum in Paris. What audacity! What a genius! Since February 12, 2019, the museum has presented an unprecedented selection of some fifty haute couture models in all its exhibition spaces. In addition to the major themes structuring the couturier's work, the new route covers two major creations: the famous Mondrian dresses (autumn-winter 1965) and the dresses created in collaboration with the artist Claude Lalanne (autumn-winter 1969). The Yves Saint Laurent Paris Museum exhibits the couturier's work in the historic site of his former fashion house, through a retrospective tour and temporary thematic exhibitions presented successively. This new presentation reflects both the creative genius of the designer and the process of creating haute couture collections. More than just a simple monographic museum, it is also a witness to the history of the 20th century and a haute couture that accompanied a certain art of living that has now disappeared. Set designer Nathalie Crinière and decorator Jacques Grange, both of whom have collaborated on many of the Foundation's projects, have redesigned its exhibition spaces in the original atmosphere of the haute couture house.
