Seamly2D is pattern design software to create reusable, scalable, sharable custom-fit patterns with using classical, couture and bespoke pattern techniques. Seamly2D saves time and improves fit by creating patterns that are reusable parametric CAD engineering documents.

Unlike other pattern design software, Seamly2D allows designers to have complete control of the patternmaking process. Each reusable, scalable pattern can read multi-size tables for boutique sizing and read individual measurement files for custom-fit.
