Throughout this time, Merryn’s strong vision and business nous caught the eye of the top industry judging panels and achieved outstanding accolades. Becoming a finalist for the prestigious VAMFF National Designer Award, as well as entry into the 'money-cant'-buy' Project Next Gen for Mercedes-Benz Fashion Week Australia.

Together; Merryn's values, design signature and recognitions are today epitomised in THIRD FORM.



THIRD FORM seeks to emulate and enliven the iterations of the modern woman – not to stifle or capture it.

Showcasing the complexity of a woman is intrinsic to THIRD FORM design, and with complexity comes a series of seemingly paradoxical dualities: sensuality and sophistication and a commanding yet understated raw energy. THIRD FORM is a vision that encourages a complete, unabashedly embrace of this polarity.

Renowned for delivering collections that deliver harmony between progressive garment design and the everyday practicality of the modern
woman’s wardrobe. Pieces are infused with a flavour of minimalism, an appreciation for fabrications and texture and are designed with an intrinsic consideration of the contours of the body.

Creating styles that appear uncomplicated and simple yet leave a lasting impression. Underpinned by a deep consideration and respect for the craft and quality of each individual garment.

The TF woman exudes confidence and is brave in her direction.

She captures your gaze; her eyes are alluring with a glint of unbounded
creativity. She is an individual. An educated tastemaker. Covert and subtle in her sensuality, you find yourself fascinated for a reason inexplicable and difficult to define.

She is impact.  

Third Form is sold in over 80 stores globally including key retailers Ounass, Moda Operandi, Luisa Via Roma, Myer and more.



At the heart of THIRD FORM is a deep consideration and respect for the craft and design process of creating each individually garment to the best of our ability.

With a design approach that sees an obsessive play between structure, shape and texture, we aim to create collections that deliver harmony between progressive garment design and the modern woman’s wardrobe, underpinned by considered premium fabrication and in-house designed artwork interpreted into prints our artisanal fabric mills.

We begin the process with detailed sketches and considered fabric selection, sketches then transform from pen to colour and the vision starts to take shape, we then work with draping and toiles before the final pieces are made with care
and attention to detail by our partners.

There’s a sophisticated sensibility to collections that extends beyond its considered palette to the more pared-down, simplified shapes that have been brought to life with texture and a play on proportions, always with the THIRD FORM edge.
