The problem

You've given your measurements
to every new brand.
They kept them. You didn't.

Every tailor, every MTM brand, every bespoke atelier has asked you the same questions. Chest, shoulder, waist. Every time, that data disappears into their system. Size Passport is the missing infrastructure — a single, permanent record that travels with you, not with them.

Ownership

Your measurements, stored once. Used everywhere.

Record your body data in Size Passport and it becomes your permanent reference. No brand can lock it away, modify it, or delete it. The record belongs to you — complete with every version, every update, every timestamp.

Portability

Your fit follows you. Across every brand.

Share your Size Passport record with any compatible brand, tailor, or atelier. Instant access to your measurements. No re-entering data. No measurement errors. One source of truth — always current, always yours to revoke.

Control

You decide who sees what. And for how long.

Grant access, revoke access, set expiry. Your Size Passport record is not a permanent handover — it's a controlled share. Every brand sees exactly what you choose, nothing more.

“I've ordered from four different tailors in the past two years. Finally having one place where all of it lives — and that I actually own — changes how I think about getting dressed.”
