Longitudinal fit continuity
The preserved record of how measurements, garments, and preferences evolve over time.
Definition
Fit Memory is the temporal history layer within Size Passport that version-controls body measurements, garment outcomes, and fit preferences over time — making the record cumulative and longitudinal rather than a single frozen snapshot.
For the person
It means the system remembers what changed, when it changed, and what that meant in practice.
For the ecosystem
Memory increases switching costs in a customer-beneficial way: the record becomes more valuable with time and repeated use.
Why it matters
Body shape, preferences, and garment behavior evolve. A useful fit system must remember that evolution.
Version-controls body measurements and fit-relevant observations.
Attaches time, operator, and garment context to each change.
Lets future operators see patterns instead of isolated records.

Body identity layer
A passport becomes richer when it remembers successive states.
Interpretable fit knowledge
Without history, fit reasoning cannot learn from change.
Trusted system for shared fit records
Longitudinal continuity requires storage rules that outlast a single operator relationship.
Questions answered clearly
Because fit is dynamic. Measurements, preferences, and construction choices change over time and need context.
No. It directly improves future fittings, alterations, and operator decisions.
Any measurement update, fitting session result, or garment outcome recorded by the customer or an approved operator. Each entry is timestamped and attributed to its source — customer, atelier, or brand.
Yes. Size Passport preserves every version of your measurements and fitting history. You can view, compare, and reference any previous state — the record is designed to be a usable longitudinal timeline, not just a stored archive.
