Who We Are

Hi, I'm Billie Cassidy, founder of Siminal Clothing.

Siminal Clothing was born from two passions that have shaped my life: wildlife conservation and thoughtful, minimalist design.

After studying wildlife conservation, I developed a particular interest in primate conservation and the incredible diversity, intelligence, and importance of primates around the world. At the same time, I've always appreciated clean, timeless design and the way clothing can express identity and values.

Over the last year, I've been developing Siminal Clothing with the goal of bringing these two passions together.

Why Siminal?

I wanted to create more than just another clothing brand. My vision was to build a brand that celebrates the natural world through modern, wearable design, while creating opportunities to support the conservation causes that have always inspired me.

Our designs use clean, minimalist line art to showcase some of the world's most fascinating primates, creating clothing that is stylish, versatile, and meaningful. Every piece is created with the intention of sparking curiosity, encouraging conversation, and building a community of people who care about the world around them.

The Bigger Picture

Siminal Clothing is still at the beginning of its journey. Right now, my focus is on building a strong, independent brand that produces high-quality clothing and connects with people who share a passion for wildlife, conservation, and great design.

As the brand grows, my ambition is to support primate conservation through charitable contributions, collaborations with conservation organisations, and increased awareness of the challenges facing primates and their habitats. I also hope to transition towards more sustainable materials and production methods as the business develops.

Looking Forward

Siminal Clothing is still at the beginning of its journey, but my ambition remains the same: to build a brand that celebrates primates, creates great clothing, and one day contributes directly to the conservation efforts that inspired it.

Style that stands up for the wild and those swinging through it.

Thank you for being part of the journey.
