Work with companies to develop first pattern. This can be done through a basic sketch, and company fit measurements, a spec, an existing garment or a technical sketch and fit measurements.
Clients can request the creation a first mockup of style (recommended), also known as a 'dummy' or 'muslin'. This is cut in muslin or an inexpensive cotton fabric. This is an additional service, but will insure the client's pattern is 'proven'. If any issues are detected in the sewing of the mockup, they will be adjusted on the pattern and a new mockup will be cut for the client at no additional charge.
The mockup is a rough unfinished garment, cut to insure that the notches match up and the pieces fit together seamlessly. This can be used to fit, though the client must keep in mind that the fit may change when cut in production fabric (all fabrics react differently to steam, pressing, etc)
Can additionally work with client's fit notes to adjust pattern for production. It is recommended that after each change in pattern, a sample is made Pre-Production to ensure there are no issues in production stage.
