This necktie from Paco Rabanne takes a traditional medallion design and updates it with larger shapes and a wider, bolder color palette. Originally a jewelry designer, Rabanne (born Francisco Rabaneda Cuervo) launched his own fashion house in Paris in 1966. His use of metal as a dress fabric has inspired an enigmatic short story, "The Dress" by Elizabeth Brown, published by David Longhorn in Issue 17 of his excellent Supernatural Tales journal. (Note that there is a free PDF edition if you feel inclined to read the story right now.)
Continuing the molecular theme, here's another pattern that looks like molecules zipping and caroming randomly around their medium. It's a black-and-white monotone print on patterned silk jacquard, with the label printed on the back: "Design by LOFT Eternal Veri-ties"-- adding some metaphysics to the physics.
