I've been looking at Delphine Desveaux' mostly pictorial Fortuny
to learn a bit about the creator of the fabulous Delphos dress. Spanish by birth but a Venetian by residence and inclination, he was one of those multi-talented people with an encyclopedic mind from which he drew inspiration from many sources for his work as an artist, set designer, photographer and furniture designer, only turning to couture at the age of forty.
He invented and patented the silk-dyeing and pleating processes he used - "The pleating of the material was achieved by a process of evaporation: the wet and folded silk was laid on heated porcelain tubes, permanently fixing such tight pleats...so that the dresses looked carved, or pressed. The effect was that they elongated the women who wore them, just like Murano craftsmen draw out their molten glass." His clothes were so distinctive that they appear often in novels, such as L.P. Hartley's Eustace and Hilda.
There is a Fortuny Museum in Venice (though it appears to be closed for renovation at present) and you can find out more about Fortuny on this website - go to Gallery, then Fashion to see the clothes. I'd like the dark blue Delphos; how about you?
