Founded as a ready to wear line by sisters Nicky and Simone Zimmermann, the label soon expanded into swimwear and won an immediate, loyal following among Australias tastemakers and trendsetters by being one of the first brands to fuse swimwear with fashion. The blending together of flattering, sexy silhouettes with bold color & print choices allowed Zimmermanns sculptural bikinis and one-pieces to become the new point of reference for haute swimwear while its ready to wear collection took their signature style from the beach to the streets. In addition to swim and ready to wear, Zimmerman has extended into kids and accessories, truly making it a lifestyle destination.
