Step 1 · T-shirt & Long sleeve

Technical pattern intelligence for serious garment makers.

PlanCollections converts body measurements, market size standards, fit profiles and real fabric properties into a structured pattern recipe and tech-pack draft — grounded in production logic, not aesthetics.

How it works

Four inputs. One structured pattern recipe.

Measurements
ISO body measurements or a regional size standard (EU, US, JP, CN).
Fabric profile
GSM, width, stretch, recovery, shrinkage — modelled like a material spec sheet.
Fit logic
Slim, regular, relaxed, oversized — driven by named ease deltas.
Tech-pack draft
POM, BOM, construction notes & exportable PDF/JSON/CSV.
Roadmap

A modular pattern OS, built one garment at a time.

v1 ships T-shirt and long sleeve. Future modules unlock as the parametric pattern engine matures.
