Fit knowledge belongs
to the person it describes.

Caprice Bespoke is a made-to-measure atelier that has worked directly with clients on bespoke jackets, shirts, trousers, and knitwear. The work is hands-on: measuring, fitting, adjusting, delivering.

What became clear, order after order, was that fit knowledge was being lost. Measurements taken during one fitting rarely survived to the next. A client who had built a detailed fitting history with one tailor would start again from zero with another. The same questions, the same tape measure, the same process — repeated indefinitely.

The problem was not technical incompetence. It was structural: there was no neutral place for this knowledge to live, no format it could travel in, no owner other than whoever held the last order file.

Size Passport is an attempt to solve that structural problem at its root. Rather than building another tailor's software or another brand's CRM, we built a record that belongs to the person being measured — not to any single business that measures them.

It stores body measurements, garment measurements, fit history, and fitting notes in a single portable record. Customers can carry it across brands, ateliers, and fittings. They can share it with a new tailor in seconds. They can export it, audit who has accessed it, and revoke access at any time.

A measurement taken today should remain useful in three years, with a different tailor, on a different continent — without asking the customer to start again.

Fashion's dependence on imprecise sizing and speculative production creates real costs: excess inventory, garment waste, returns that are discarded rather than resold, and a persistent gap between what is made and what actually fits.

These are not inevitable inefficiencies. They are, in large part, a consequence of fragmented fit data and the absence of any shared infrastructure for moving that data between the people and businesses involved in making clothes. Better fit intelligence — owned by the wearer, shared with permission — is one of the most direct levers for reducing this waste.

We are interested in addressing problems at their root cause, not treating symptoms. Fit data portability is one root cause worth fixing.

Infrastructure that people depend on — infrastructure that holds personal data, that touches how people access services, that mediates relationships between individuals and institutions — should not be run for profit. Its incentives need to be aligned with the people it serves, not with extracting value from them.

We believe certain things should remain at the service of the whole — not captured by any single commercial interest. Size Passport is being built toward that model. The goal is a non-profit structure that can sustain the infrastructure without depending on monetising the data it holds or the access it enables.

Caprice Bespoke is the originating brand and the first real-world context in which this infrastructure is being tested. It does not own Size Passport. It is a participant — and the reason it exists.

Customers remain the reference point for access. No brand or atelier receives fit data without an explicit, individual grant. Contributions made by a brand are attributed and visible to the customer. Access can be revoked. Export remains available from the customer dashboard at any time.

The permission model is intentionally simple: you own the record, you decide who sees it, and you can always take it with you. Size Passport does not sell data. It does not use fit records to build advertising profiles. The business model that would require doing so is the business model we are explicitly not building.
