Design a four-look capsule from what already exists.

Three wearable looks and one showpiece. We're looking for designers who can make constraint produce better clothes, not worse ones — a considered material strategy, not a sustainability claim attached after the fact.

At least 60% of each look, by surface area, must come from one or more of the following:

• Deadstock or end-of-roll fabric — unused yardage that would otherwise be discarded
• Post-consumer garments or textiles — reworked, reconstructed or disassembled
• Offcuts and factory waste — including your own studio waste
• Certified recycled fibre — minimum 50% recycled content
• Natural fibres to a recognised standard — organic, regenerative or equivalent, certification named

• 18 or over at the date of entry
• Currently enrolled at a college or university, or graduated within the last three years
• Fewer than four years of professional fashion design experience — internships and study do not count
• Individual entries only. One entry per designer
• Open internationally. Travel to Los Angeles is the winner's own arrangement

How entries are judged

Sustainability and material innovation — 40%. Rigour of sourcing, honesty of the claim, and whether the constraint made the work more interesting.

Creativity and originality — 35%. A point of view we have not seen thirty times this season.

Wearability and construction — 25%. Assessed at the final stage, on finished garments.

Judged by the SFWRUNWAY production team alongside industry judges and faculty judges nominated by partner institutions.
