Third Form

Third Form brings a fresh edge to refined dressing. Comprised of thoughtfully designed stapes, with a unique twist,read more the contemporary label makes dressing well look effortless. The Third Form aesthetic was created by Merryn Kelly, who worked as an in-house designer and some of Australia’s leading fashion labels. Inspired by modern women living busy lives in urban environments, she sought to create truly versatile pieces - the space where workwear pieces and off-duty wardrobes collide. The resulting style includes inventive use of texture, fabric, and structure to create a perfectly polished yet casual look. Noteworthy Third Form fans include Nadia Fairfax, Margaret Zhang, and Vanessa Hong.
