St.Clair Design Collective specialise in technical fashion design and strategic design development. Founded and led by Sarah St.Clair, the studio supports fashion start-ups, emerging designers and established brands to move confidently from concept to production.

St.Clair Design Collective was established to bridge the gap between creative ideas and manufacturable garments by providing production-ready tech packs, strategic brand support, and fashion business mentoring. We translate concepts into clear, professional documentation that manufacturers understand — helping clients reduce risk, avoid costly mistakes, and streamline the production process.

As Founder and Lead Consultant, Sarah St.Clair brings industry-led expertise in technical fashion design, tech pack development, and production communication, ensuring garments are prepared for manufacturing and scale.

To further support fashion founders beyond production, St.Clair Design Collective partners with Jude Kingston, a highly respected fashion industry expert with 30+ years of global retail and fashion experience. Jude provides fashion business mentoring and strategic advisory services, supporting clients with brand positioning, product ranging and assortment, customer identification, growth planning, and expansion across multiple channels and international markets.

Through this partnership, clients gain access to a global fashion network, with industry connections spanning Brisbane, Sydney, Melbourne, and New York.

At St.Clair Design Collective, we are committed to purpose-led and ethical fashion. By combining technical expertise with strategic business insight, we help fashion brands build strong foundations, produce with confidence, and grow sustainably in a fast-evolving global marketplace.
