Nicky and Simone Zimmermann founded their namesake label in Sydney in 1991. The business began with Nicky designing and making garments in her parents' garage during the week and selling dresses at Paddington Markets on weekends.

An editorial appearance in Australian Vogue generated boutique orders and accelerated the young business. Simone joined Nicky in 1991, establishing the partnership that would become fundamental to Zimmermann's long-term growth.
