Neoprene is a synthetic, spongy material (foamed synthetic rubber), known primarily as the fabric of wetsuits thanks to its water resistance and ability to retain heat. Neoprene entered fashion in the 2010s, when designers appreciated its unique property — a density and springiness that lets the fabric hold a clean, almost sculptural shape. Neoprene pieces do not cling but 'stand', creating voluminous, graphic silhouettes, so it is used for structured dresses, skirts, tops and jackets. The material is pleasantly dense, holds the geometry of a cut well and does not crease. It is often used in sportswear and avant-garde clothing. Neoprene is a modern, 'technological' material, in which a sports origin and unique structural quality open up possibilities for designers to create bold, architectural forms.
