Diffusion line

A diffusion line (also known as a bridge line) is a secondary line of merchandise created by a high-end fashion house or fashion designer that retails at lower prices. These ranges are separate from a fashion house's "signature line", or principal artistic line, that typically retail at much higher prices. Diffusion products may be on sale alongside designers' signature line but they can also be made available at concession outlets and certain chain stores. The use of a diffusion line is a part of the strategy of Massification where luxury brands attempt to reach a broader market in order to increase revenue and brand recognition.
