Trickle-up effect (fashion) (original) (raw)

The trickle-up effect in the fashion field, also known as bubble-up pattern, is an innovative fashion theory first described by Paul Blumberg in the 1970s. This effect describes when new trends are found on the streets, showing how innovation flows from the lower class to upper class. It is in contrast with classical theories of fashion consumption, such as those of Georg Simmel and Thorstein Veblen, who theorize that the upper classes are the ones who dictate the fashion flow.
