Schiaparelli's Circus Collection
Elsa Schiaparelli is somewhat of a legend in the fashion industry, mostly known as the Surrealist foil and foe of contemporary Coco Chanel. She is a constant reference point for an avant-garde, intellectual, and artistic approach to design, having been connected with the Surrealist movement and even collaborating with Salvador Dali. A fascinating figure—I highly recommend at least skimming over her Wikipedia page!
Many Schiaparelli works are now museum pieces, and it's not hard to see why. The level of creativity, innovation, craftsmanship, and frankly, shock-power, is sure to garner study and attention for years to come.
The one collection that I've found particularly inspiring as of late is her 1938 Circus Collection, which is representative of many of Schiaparelli's collections in its bold use of thematic subject matter, illustrative motifs, heavy embellishment, and custom collaboration with other artists.
