A Note from the founders

By Sid was created by sisters Hayley Crannage and Jayde Hayfield, born from a shared love of fashion, design, and building brands with meaning.

After founding and growing a highly successful eyewear business that was later acquired, we felt a strong pull to expand into apparel an extension that felt both natural and deeply personal. Clothing has always been where we express ourselves most, the quiet confidence of a great jacket, the ease of well cut denim, the power of pieces you reach for every day.

We are grounded in hard work, intention, and the belief that great brands are built slowly and thoughtfully. Inspired by legacy fashion houses that endure beyond seasons, By Sid is designed to tell a story, one of purpose, longevity, and connection.

Inclusivity sits at the heart of everything we do. We believe fashion should feel accessible, empowering, and reflective of the women who wear it. Our community is not an afterthought, it is the foundation. Our customers are the pillars of the brand, shaping how By Sid grows, evolves, and shows up in the world.

By Sid is our way of building something lasting.
Designed with intention.
Worn with confidence.
Built with community at its core.
