Founded in 2016 by Danielle Mulham, Posse is an Australian womenswear brand with a devotion to quality, material and make. 

We choose fabrics not only for their beauty, but for how they feel, wear, and last. And we build seasonal collections to become part of a woman’s everyday life, with ease, clarity and lovely little details. 

Our world is shaped by curiosity. By people and places, old books and films, forgotten objects, antiques collected along the way and stories worth retelling. We look beyond fashion for inspiration, drawn instead to the beauty found through connection, discovery and a sense of nostalgia.

From its beginnings in Australia, Posse has found its way into wardrobes around the world, and is now available through more than 80 global stockists including Net-a-Porter, Moda Operandi, MyTheresa, Le Bon Marché, Lane Crawford, Selfridges, and Nordstrom. 

In 2026 we launched our very first flagship store in New York City. 

Still to this day, Posse is a family run, privately owned business.
