Methods and systems for manufacture of a garment

A method of generating fabrication data for manufacture of a brassiere, said brassiere for support of at least one breast in a bust region of a wearer of the brassiere, the method comprising:

• obtaining unsupported breast measurement data for the at least one breast in the bust region, with the least one breast in an unregulated, unsupported and downwardly oriented position under gravity;
• setting an initial arrangement of a three-dimensional model for the at least one breast in the bust region to reflect the unsupported breast measurement data;
• modifying the unsupported breast measurement data to simulate an upwardly displaced regulating effect of the brassiere to displace the at least one breast upwardly from the unregulated, unsupported and downwardly oriented position to a relatively upward position in an upwardly displacing regulated state by modifying the unsupported breast measurement data to simulate the relatively upward position in the upwardly displaced regulated state, to form modified upwardly displaced supported breast measurement data;
• checking the upwardly displacing regulating effect on the three-dimensional model for the at least one breast in the bust region against the modified upwardly displaced supported breast measurement data;
• and
• using the modified upwardly displaced supported breast measurement data to generate the fabrication data for manufacturing the brassiere.
