Many gowns aim for the appearance of grace, fluidity and movement. Rihanna's dress, at the Glamour Women of the Year Awards, seems to be going for a stop-motion effect.
Nude Descending a Staircase, No. 2, by Marcel Duchamp. Anyone else see the resemblance? When Duchamp debuted this painting, critics loathed it and said it looked like "an explosion in a shingle factory." But, it turned out that the world had never seen quite an explosion, and the painting stuck and became an iconic image of the 20th century. I cannot help but feel the designer of Rihanna's dress was inspired, either consciously or subconsciously, by Marcel Duchamp.
If given the opportunity, go to the Philadelphia Museum of Art to see this painting. It's even better in real life.
