Founded by sisters Natacha Lacosse and Martine Lacosse, Acossi Jeans grew from a shared passion for fashion, design and individual expression. Natacha’s background in fashion and graphic design, together with Martine’s eye for styling, helped shape a brand rooted in denim while always looking beyond it.
The early collections explored denim, jackets and contemporary separates with an emphasis on fit, detail and character. Inspiration came from the streets as much as the runway—from New York to Paris and Milan—shaping an Acossi point of view that balances urban energy with a refined, wearable sensibility.
For Natacha, design has always extended beyond clothing. Her experience in creative direction, graphic design and product development has influenced Acossi from product design to visual presentation. Martine’s styling perspective brings another dimension to that vision, creating a natural creative partnership between the two sisters.
As the brand developed, Acossi reached international audiences through fashion events and presentations, with appearances in Milan, Hong Kong and Shanghai. These experiences became part of the brand’s story, bringing its collections and creative vision to an international stage.
Through each stage of its evolution, Acossi has remained connected to the philosophy that inspired its beginning: fashion should feel individual, expressive and relevant to the way people live.

Acossi Jeans is a contemporary fashion and lifestyle brand whose identity extends beyond denim. While jeans remain part of its heritage, Acossi has evolved through clothing, handbags, accessories and selected lifestyle pieces that reflect a broader approach to personal style.
At its core, Acossi is not defined by a single category. The brand brings together modern design, distinctive details and an expressive point of view—creating pieces that move naturally between casual, polished and individual style.
That same creative perspective extends into a curated collection of personalized and custom products for businesses, events and gifting. Each addition is selected with the Acossi aesthetic in mind, allowing customization to become part of the brand’s lifestyle offering rather than a separate promotional catalog.
With denim as part of its foundation—not its limitation—Acossi continues to explore the relationship between fashion, lifestyle, design and personal expression.
